You're looking at this the wrong way. $150 coins aren't cheap. They're ridiculously overvalued. The only thing Bitcoin's "good" for is buying illegal stuff on the deep web. The blockchain can handle a whopping 2.7 transactions per second, which makes Bitcoin completely useless as anything resembling a mainstream currency. After this Gox bubble/speculation phase, Bitcoin will go back to a reasonable and sustainable value which reflects its potential as a deep web currency for criminals. That value is somewhere in the double or single digits.
Bitcoin had its fifteen minutes of fame.
Large investors put money in Enron too, shortly before it went bankrupt. It's not uncommon for rich people to make bad investments.
it would only fail if we let it fail and i wont ,and i know many others who will continue using it and supporting it
its not a company that can go bankrupt
thats one of the mains strengths of btc ,there is no greedy CEO to make bad decisions
