10 Physical Bitcoins: The Good, The Bad and The Ugly
Anyone wanted to buy a Casascius Bitcoin but was afraid to?
so i've been wanting one of these for a while and the thing holding me back is that it is known that the hologram can be removed and reapplied with the average person not being able to tell it was tampered with. Does this idea bother anyone else? A malicious seller could sell a fully "loaded" coin and have done what these hackers did. You check the casascius checker sites and it's unredeemed but unknowingly the seller already has the private key waiting to sweep it after you pay a premium https://99bitcoins.com/defcon-hacking-conference-casascius-physical-bitcoins-get-cracked/
Anyone want to buy an original 25btc Casascius Physical Bitcoin?
I would like to sell a 25btc casascius coin, with a hologram fully intact. Would be happy to arrange an escrow deal, where a 3rd party holds money until buyer receives coin. I would ask for 29btc but am willing to take offers / negotiate. feel free to pm me :)
2011 1-btc brass error>> 1.3BTC ms65 graded , price 1.2btc What do you guys think? Good deal? I want a coin like this but it seems like the premium on these coins has been coming down recently. I appreciate your time! --------------------------------------------------------------------------------------------- This would be escrowed through: "minerjones" on bitcointalk forum He has 113 trust, 10596 posts and his proflie is the following: https://bitcointalk.org/index.php?action=profile;u=346731
How can you possibly verify a physical coin contains its bitcoin. Without breaking the hologram and sweeping the wallet? If I were sneaky. I would buy a Casascius coin, Duplicate it. And sell my "chain of custody" coin, over and over again. The only way i get caught. Is if someone opens their coin and sweeps the wallet. This alerts everyone else (if they are looking), that they've been had. There is nothing particularly special about these coins to prevent duplication. And a huge $ incentive to rip them off. I'm intrigued if I am missing something. People still buying these things, at significant premiums. Based solely on idea they aren't possible to fake? I have asked this question in a bunch of places. And I would like to know why they are given such a premium. I spent 10 years in China. And went to a talk years ago by a researcher who uses pollen grains to track fake medical products coming from southern China. They change the holograms regularly, but it doesn't stop the fakes. And I think that pharma companies have more resources than Mike, and others, making these physical objects. I don't understand the resale market for these objects. Would appreciate a discussion.

What can the earlier days of Bitcoin teach us about holding Ethereum?
Recently, I was thinking back to my first exposure to crypto, after talking with a couple of my coworkers who shared their own, more recent experience with me. It was late 2013 when I first bought BTC, but I had heard about Bitcoin a couple of years earlier. I thought the idea of internet money that nobody controlled sounded like a scam, so I stayed clear. I couldn't really understand the value proposition and didn't take the time to understand how it works (hindsight is 20/20). That started to change in early 2013. I learned much more about Bitcoin, which at the time was the only blockchain of any consequence, and began to understand the trustless nature of this revolutionary technology and how it would change the world. But what drew me in was the price. For those of you who weren't around then, it's worth taking a minute to open up that chart on Coinbase and see what that bump was in the grand scheme of things. See what now looks like a relatively little blip there in late 2013? That was when Bitcoin went roughly 10x in a month- from a $100 valuation to a $1000 valuation. I signed up for a Coinbase account shortly before Thanksgiving. Over that Thanksgiving, I spent the whole holiday / weekend talking to my family about how revolutionary this technology was- and wow, were they confused and unable to fathom it. To me, it seemed so obvious. Price increases have a way of "revealing" unassailable logic in situations like these. It took a while for Coinbase to approve my account, but I could hardly wait for that. I was on eBay, seeing if I could buy Casascius Coins. They were appealing to me at the time, because they merged an asset that was completely virtual with something that was tangible. My brain had still not fully accepted paying so much money for something that "didnt' exist" in real life. But the speculation was soaring so high on those coins (double the BTC value or more) that I decided to pass. Soon thereafter, I finally got access to Coinbase and bought my first Bitcoin for around $900. And then the price dropped, and it kept dropping. But I kept on buying, knowing that this is how asset markets worked. The price was going down, but for something this revolutionary, it would have to eventually go back up...at least that's what I was hoping. I bought all the way down to prices in the low $400s. And then in June 2014, I abruptly sold them all, at a sizable net loss. Why did I do that? What was going through my mind to make such a rash decision? Well, open that chart back up. The price had cratered down into the $230s and seemed to be stuck at these new lows- it was a winter that started earlier in that year and never ended. And the Mt Gox debacle was completely soul crushing and I really felt that my hopes for the success of a decentralized currency were completely dashed. And back then, there were no other alt coins to FOMO into. It was Bitcoin or (mostly) nothing. Besides, I had a major home purchase underway and decided that my money was better going into that rather than holding Bitcoin. In hindsight, I sold at what turned out to be the close to the bottom of Bitcoin. And then just look at that chart. A slow and steady increase over years, with $1000 only being reached again in March of this year. And as we enter Thanksgiving 4 years later, some of you are going to have these same conversations with your own families about Ethereum. I can tell you what some of them are going to say: "Internet money? I wouldn't invest in something like that. Who controls it? Isn't this just for criminals?" "Smart contracts? Even if they do work, what's the point of having them when you have regular contracts? And why does XYZ service even need to be decentralized?" "This whole thing sounds like a bubble. I hope you don't have much money in this..." So what does all of this teach us about holding Ethereum?
For many of your friends and family next week, it will be the first time they've heard of concepts like smart contracts or even cryptocurrency in any depth, but if Bitcoin is our teacher, it won't be the last. Take the time to explain it, but don't be pushy about it. Plant the seed, walk away, and send articles to them over the course of the next year.
Bitcoin's $1000 moment reminds me of ETH's $420 moment. Many new buyers FOMO'ed in and are still waiting for their returns, with many likely abandoning the path along the way. Most of the actual buyers of Bitcoin in 2013 then were "nerds" who were fascinated by the technology because they were among the few who took the time to understand it and felt comfortable putting large amounts of money into something on the internet. I would suggest that most recent ETH buyers are still in this "nerd" territory, without real mainstream understanding of what it is.
We are in what seems like a "long winter," with ETH stagnant at around $300. But it is unlikely our next big run will take 4 years to develop. I'm thinking a period of 3 to 12 months. The space isn't what it used to be, with massive institutional money coming and a very vibrant and mainstream-accepted development community. Those among you who were smart bought every token they could during the July depression. If that happens again, you know what to do.
Even if we had another Mt Gox style event (I won't name any exchanges or pegged tokens), it would probably not have the same impact as Mt Gox had. The system is much more diverse and resilient against such events now. There would be a drop, but it would be (hopefully) short lived.
If you just hold long enough, the price is very likely to go up. Possibly substantially up. Maybe even life changing amounts up. You understand the technology and the potential. Don't doubt yourself on your original thesis, like I did with Bitcoin a few years ago. The future picture for ETH has only gotten better in recent months.
So learn from Bitcoin, and don't screw this up for yourselves by taking rash actions- driven by impatience or outsized greed. I am not always one for hyperbole, but I am not exaggerating when I say that you may honestly regret it for the rest of your life.
If I buy a Casascius coin will I be able to retrieve all the other forked coins from it or am I just getting the bitcoin value? If so, how is it done? Do I have to sweep it like a paper wallet? This is from a trusted party that purchased the coin straight from Mike Caldwells in 2011, ya, it's the one with a hologram error. Asking for a friend. HODL
I'm poor and currently own One Casascius Bitcoin and Fifty Five Dash. Advice one what I should be doing with it?
A long time ago a friend of mine introduced me to Bitcoin and I bought 6 of them for $50 a piece. When the price doubled I sold half and got my original investment out. Since then I've traded a little and lost some but ended up owning 1 physical Casascius Bitcoin and 55 DASH. I've held on to this amount for years now. I had some money saved up and quit my dead end job to finish studying for the CCNA exam and am now left wondering what to do with it. I currently have enough saved to live on for the next 6 months but I cant decide what to do with these coins? Any advice? I could sell them all, 15K each week till they were gone. I could sell all but 20%. I could sell all the DASH and keep the physical Bitcoin, which is hard to sell. I can't decide what to do. Each time I've sold a little I end up regretting it, but holding on to them makes me worry. That in six months they may no little value when I need them too. Of course, I should have the CCNA done and a new job by then. Any advice is appreciated.
Lightning Network Will Likely Fail Due To Several Possible Reasons
ECONOMIC CASE IS ABSENT FOR MANY TRANSACTIONS The median Bitcoin (BTC) fee is $14.41 currently. This has gone parabolic in the past few days. So, let’s use a number before this parabolic rise, which was $3.80. Using this number, opening and closing a Lightning Network (LN) channel means that you will pay $7.60 in fees. Most likely, the fee will be much higher for two reasons:
BTC fees have been trending higher all year and will be higher by the time LN is ready
When you are in the shoe store or restaurant, you will likely pay a higher fee so that you are not waiting there for one or more hours for confirmation.
Let’s say hypothetically that Visa or Paypal charges $1 per transaction. This means that Alice and Carol would need to do 8 or more LN transactions, otherwise it would be cheaper to use Visa or Paypal. But it gets worse. Visa doesn’t charge the customer. To you, Visa and Cash are free. You would have no economic incentive to use BTC and LN. Also, Visa does not charge $1 per transaction. They charge 3%, which is 60 cents on a $20 widget. Let’s say that merchants discount their widgets by 60 cents for non-Visa purchases, to pass the savings onto the customer. Nevertheless, no one is going to use BTC and LN to buy the widget unless 2 things happen:
they buy more than 13 widgets from the same store ($7.60 divided by 60 cents)
they know ahead of time that they will do this with that same store
This means that if you’re traveling, or want to tip content producers on the internet, you will likely not use BTC and LN. If you and your spouse want to try out a new restaurant, you will not use BTC and LN. If you buy shoes, you will not use BTC and LN. ROAD BLOCKS FROM INSUFFICIENT FUNDS Some argue that you do not need to open a channel to everyone, if there’s a route to that merchant. This article explains that if LN is a like a distributed mesh network, then another problem exists:
"third party needs to possess the necessary capital to process the transaction. If Alice and Bob do not have an open channel, and Alice wants to send Bob .5 BTC, they'll both need to be connected to a third party (or a series of 3rd parties). Say if Charles (the third party) only possesses .4 BTC in his respective payment channels with the other users, the transaction will not be able to go through that route. The longer the route, the more likely that a third party does not possess the requisite amount of BTC, thereby making it a useless connection.”
CENTRALIZATION According to this visualization of LN on testnet, LN will be centralized around major hubs. It might be even more centralized than this visualization if the following are true:
Users will want to connect to large hubs to minimize the number of times they need to open/close channels, which incur fees
LN’s security and usability relies on 100% uptime of relaying parties
Only large hubs with a lot of liquidity will be able to make money
Hubs or intermediary nodes will need to be licensed as money transmitters, centralizing LN to exchanges and banks as large hubs
“…applicability of the regulations … to persons creating, obtaining, distributing, exchanging, accepting, or transmitting virtual currencies.” “…an administrator or exchanger is an MSB under FinCEN's regulations, specifically, a money transmitter…” "An administrator or exchanger that (1) accepts and transmits a convertible virtual currency or (2) buys or sells convertible virtual currency for any reason is a money transmitter under FinCEN's regulations…” "FinCEN's regulations define the term "money transmitter" as a person that provides money transmission services, or any other person engaged in the transfer of funds. The term "money transmission services" means "the acceptance of currency, funds, or other value that substitutes for currency from one person and the transmission of currency, funds, or other value that substitutes for currency to another location or person by any means.”” "The definition of a money transmitter does not differentiate between real currencies and convertible virtual currencies.”
"An “informal value transfer system” refers to any system, mechanism, or network of people that receives money for the purpose of making the funds or an equivalent value payable to a third party in another geographic location, whether or not in the same form.” “…IVTS… must comply with all BSA registration, recordkeeping, reporting and AML program requirements. “Money transmitting” occurs when funds are transferred on behalf of the public by any and all means including, but not limited to, transfers within the United States or to locations abroad…regulations require all money transmitting businesses…to register with FinCEN."
Mike Caldwell used to accept and mail bitcoins. Customers sent him bitcoins and he mailed physical bitcoins back or to a designated recipient. There is no exchange from one type of currency to another. FinCEN told him that he needed to be licensed as money transmitter, after which Caldwell stopped mailing out bitcoins. ARGUMENTS AGAINST NEED FOR LICENSING Some have argued that LN does not transfer BTC until the channel is closed on the blockchain. This is not a defence, since channels will close on the blockchain. Some have argued that LN nodes do not take ownership of funds. Is this really true? Is this argument based on a technicality or hoping for a loophole? It seems intuitive that a good prosecutor can easily defeat this argument. Even if this loophole exists, can we count on the government to never close this loophole? So, will LN hubs and intermediary nodes need to be licensed as money transmitters? If so, then Bob, who is the intermediary between Alice and Carol, will need a license. But Bob won’t have the money nor qualifications. Money transmitters need to pay $25,000 to $1 million, maintain capital levels and are subject to KYC/AML regulations1. In which case, LN will have mainly large hubs, run by financial firms, such as banks and exchanges. Will the banks want this? Likely. Will they lobby the government to get it? Likely. Some may be wondering about miners. FinCEN has declared that miners are not money transmitters: https://coincenter.org/entry/aml-kyc-tokens :
"Subsequent administrative rulings clarified several remaining ambiguities: miners are not money transmitters…"
FinCEN Declares Bitcoin Miners, Investors Aren't Money Transmitters Some argue that LN nodes will go through Tor and be anonymous. For this to work, will all of the nodes connecting to it, need to run Tor? If so, then how likely will this happen and will all of these people need to run Tor on every device (laptop, phone and tablet)? Furthermore, everyone of these people will be need to be sufficiently tech savvy to download, install and set up Tor. Will the common person be able to do this? Also, will law-abiding nodes, such as retailers or banks, risk their own livelihood by connecting to an illegal node? What is the likelihood of this? Some argue that unlicensed LN hubs can run in foreign countries. Not true. According to FinCEN: "“Money transmitting” occurs when funds are…transfers within the United States or to locations abroad…” Also, foreign companies are not immune from the laws of other countries which have extradition agreements. The U.S. government has sued European banks over the LIBOR scandal. The U.S. government has charged foreign banks for money laundering and two of those banks pleaded guilty. Furthermore, most countries have similar laws. It is no coincidence that European exchanges comply with KYC/AML. Will licensed, regulated LN hubs connect to LN nodes behind Tor or in foreign countries? Unlikely. Will Amazon or eBay connect to LN nodes behind Tor or in foreign countries? Unlikely. If you want to buy from Amazon, you’ll likely need to register yourself at a licensed, regulated LN hub, which means you’ll need to provide your identification photo. Say goodbye to a censorship-resistant, trust-less and permission-less coin. For a preview of what LN will probably look like, look at Coinbase or other large exchanges. It’s a centralized, regulated and censored hub. Coinbase allows users to send to each other off-chain. Coinbase provides user data to the IRS and disallows users from certain countries to sell BTC. You need to trust that no rogue employee in the exchange will steal your funds, or that a bank will not confiscate your funds as banks did in Cyprus. What if the government provides a list of users, who are late with their tax returns, to Coinbase and tells Coinbase to block those users from making transactions? You need Coinbase’s permission. This would be the antithesis of why Satoshi created Bitcoin. NEED TO REPORT TO IRS The IRS has a definition for “third party settlement organization” and these need to report transactions to the IRS. Though we do not know for sure yet, it can be argued that LN hubs satisfies this definition. If this is the case, who will be willing to be LN hubs, other than banks and exchanges? To read about the discussion, go to: Lightning Hubs Will Need To Report To IRS COMPLEXITY All cryptocurrencies are complicated for the common person. You may be tech savvy enough to find a secure wallet and use cryptocurrencies, but the masses are not as tech savvy as you. LN adds a very complicated and convoluted layer to cryptocurrencies. It is bound to have bugs for years to come and it’s complicated to use. This article provides a good explanation of the complexity. Just from the screenshot of the app, the user now needs to learn additional terms and commands: “On Chain” “In Channels” “In Limbo” “Your Channel” “Create Channel” “CID” “OPENING” “PENDING-OPEN” “Available to Receive” “PENDING-FORCE-CLOSE” There are also other things to learn, such as how funds need to be allocated to channels and time locks. Compare this to using your current wallet. Recently, LN became even more complicated and convoluted. It needs a 3rd layer as well: Scaling Bitcoin Might Require A Whole 'Nother Layer How many additional steps does a user need to learn? ALL COINS PLANNING OFF-CHAIN SCALING ARE AT RISK Bitcoin Segwit, Litecoin, Vertcoin and possibly others (including Bitcoin Cash) are planning to implement LN or layer 2 scaling. Ethereum is planning to use Raiden Network, which is very similar to LN. If the above is true about LN, then the scaling roadmap for these coins is questionable at best, nullified at worst. BLOCKSTREAM'S GAME PLAN IS ON TRACK Blockstream employs several of the lead Bitcoin Core developers. Blockstream has said repeatedly that they want high fees. Quotes and source links can be found here. Why is Blockstream so adamant on small blocks, high fees and off-chain scaling? Small blocks, high fees and slow confirmations create demand for off-chain solutions, such as Liquid. Blockstream sells Liquid to exchanges to move Bitcoin quickly on a side-chain. LN will create liquidity hubs, such as exchanges, which will generate traffic and fees for exchanges. With this, exchanges will have a higher need for Liquid. This will be the main way that Blockstream will generate revenue for its investors, who invested $76 million. Otherwise, they can go bankrupt and die. One of Blockstream’s investors/owners is AXA. AXA’s CEO and Chairman until 2016 was also the Chairman of Bilderberg Group. The Bilderberg Group is run by bankers and politicians (former prime ministers and nation leaders). According to GlobalResearch, Bilderberg Group wants “a One World Government (World Company) with a single, global marketplace…and financially regulated by one ‘World (Central) Bank’ using one global currency.” LN helps Bilderberg Group get one step closer to its goal. Luke-Jr is one of the lead BTC developers in Core/Blockstream. Regulation of BTC is in-line with his beliefs. He is a big believer in the government, as he believes that the government should tax you and the “State has authority from God”. In fact, he has other radical beliefs as well:
it is moral for the government to execute criminals and heretics (non-believers)
According to this video, Luke-Jr was the only person to have ever carried out a 51% attack, to destroy a coin that he did not like.
So, having only large, regulated LN hubs is not a failure for Blockstream/Bilderberg. It’s a success. The title of this article should be changed to: "Lightning Will Fail Or Succeed, Depending On Whether You Are Satoshi Or Blockstream/Bilderberg". SIGNIFICANT ADVANCEMENTS WITH ON-CHAIN SCALING Meanwhile, some coins such as Ethereum and Bitcoin Cash are pushing ahead with on-chain scaling. Both are looking at Sharding. Visa handles 2,000 transactions per second on average. Blockstream said that on-chain scaling will not work. The development teams for Bitcoin Cash have shown significant on-chain scaling: 1 GB block running on testnet demonstrates over 10,000 transactions per second: "we are not going from 1MB to 1GB tomorrow — The purpose of going so high is to prove that it can be done — no second layer is necessary” "Preliminary Findings Demonstrate Over 10,000 Transactions Per Second" "Gigablock testnet initiative will likely be implemented first on Bitcoin Cash” Peter Rizun, Andrew Stone -- 1 GB Block Tests -- Scaling Bitcoin Stanford At 13:55 in this video, Rizun said that he thinks that Visa level can be achieved with a 4-core/16GB machine with better implementations (modifying the code to take advantage of parallelization.) Bitcoin Cash plans to fix malleability and enable layer 2 solutions: The Future of “Bitcoin Cash:” An Interview with Bitcoin ABC lead developer Amaury Séchet:
"fixing malleability and enabling Layer 2 solutions will happen”
However, it is questionable if layer 2 will work or is needed. GOING FORWARD The four year scaling debate and in-fighting is what caused small blockers (Blockstream) to fork Bitcoin by adding Segwit and big blockers to fork Bitcoin into Bitcoin Cash. Read: Bitcoin Divorce - Bitcoin [Legacy] vs Bitcoin Cash Explained It will be interesting to see how they scale going forward. Scaling will be instrumental in getting network effect and to be widely adopted as a currency. Whichever Coin Has The Most Network Effect Will Take All (Or Most) (BTC has little network effect, and it's shrinking.) The ability to scale will be key to the long term success of any coin.
Casascius physical bitcoins, also called Casascius coins, are physical metal coins created by Bitcoin user Casascius (Mike Caldwell, Sandy, Utah, USA) and sold until Nov 26, 2013, that contain an embedded piece of paper with digital Bitcoin value, covered by a tamper-resistant hologram.Casascius coins are available in 1, 10, 25, 100, and 1000 BTC increments.
