I didn't necessary wanted to debate the possible reasons why bitcoin could fail, I just listed a bunch, because Baron asked. They were all valid reasons by the way...
Quote from Hoi:There is still a lot of known and unknown problems ahead which can "fail" (not die) this Virtual-currency experiment.
1. We don't know how alt coins will act, or how popular they will become. Just remember Myspace, the first one isn't always the winner. Now there are some venture capital companies that work on new coin systems, when they realized, "hey, you can just create your own money, and get rich by doing so"?
2. We don't know how or when the government will act. The hearings were rather (and surprisingly) positive, but the future doesn't need to be so. The US government has the means and can have the will to kill virtual currencies if they want so. If nothing else, they could just use the 140K coins and make the market extremely instabile by throwing it all at once then buying it back and keep repeating it.
3. Mass sentiment can change very quickly. The best crime usage isn't selling drugs but payment for kidnapping. Once a famous person gets kidnapped and the criminals ask for payments in bitcoins, that will be a game changer. The same if a terrorist cell gets discovered living in America, and getting paid via bitcoin.
The point is, average people can turn their back on it very fast, if certain events happen.
4. The TAX thing. Prostitution/marihuana are taxable but still mostly illegal, so that is not a good argument.
5. There can be plenty of reasons why a retailer doesn't want to deal with it, security, fearing government action,etc.
6. The coin white list is being discussed, and the government could say, they allow bitcoin usage, but only if this feature is implemented.
7. The more digits after the dot only works if price increases and that is not a given, for the already described reasons...So lost coins do cause a problem.
There can be an altcoin where lost/unused coins gets replaced repeatedly.
8. I haven't mentioned in the earlier post, but bitcoin is essentially a ponzi/pyramid scheme, and once new users stop coming in, growth stops, and once users leave, the system fails.
The bottomline is what I quoted from you, there are plenty of unknowns that can cause this experience not to work out as intended...
So we actually agree....
P.S.: One of the biggest problem of bitcoin is the fixed amount of coins. That's not how money systems operate. In a perfect world the money supply is flexible, and when there are more products and services, more money is created, when the economy contracts, the supply is withdrawn. This problem isn't addressed by bitcoin. It is a deflanionary system by design. And please don't mention the more dots behind the zero...

It is very easy to send money to the wrong person/address, and you are at the mercy of the receiving person's goodwill:

This dude has just sent 15K to the wrong address, but got lucky and they returned the coins. There is simply no law or any kind of enforcement system what could reverse the accidental action. Huge fail if you ask me....
