"In fact, it is not used much in the legal economy now. Yes, a rich man sells it to another rich man, but this is not the end use. Without these uses, it has no long-term future. ," Rogoff said. In other words, Bitcoin currently exists almost exclusively as a speculative tool.
So, is the Bitcoin bubble about to burst?
The thing is... you want to present Bitcoin as a "Rich Man" toy and that is wrong. A lot of people are buying say $5 worth of bitcoins every week and that makes it affordable for the people that are not wealthy. (Go buy some shares for $5 ....not Penny stocks)

The thing people are missing about Bitcoin's use is this... It is no different to other currencies (People trade on Forex with other currencies and they use currencies daily for commerce and the same thing is happening with Bitcoin)
Now, did we not have several other Bubbles in other financial instruments in the past? (Real Estate Stock Market Bubble Dotcom Bubble....) and guess what, they bounced back and people are still using them.

That is just the nature of any financial instrument out there, so pointing fingers at Bitcoin is just wrong.
