I want to pitch in my two cents here, it definitely wont be the last time people are asking this question about Bitcoin being a bubble. The answer is: nobody knows at this point. To say something is in a bubble, one must have some idea of the fundamental value of an asset. Even stock market bubbles are hard to spot before the fact where we do have fundamental benchmarks like the price/earnings ratio, etc. What would be the fundamental value of Bitcoin? We purely operate off the demand curve here. And the demand is based on our expectations that Bitcoin can become the next world currency or the next gold, change the world via block chain technology, create opportunities for everyone to participate in the new kind of decentralized economy.
