According to this post some professor thinks that the bitcoin bubble will eventually pop and that will be lost faster than it was made.
Last Stage of Bitcoin Bubble Yet to Occur
He base his research on what the the banks and investors do to create growth. I think this may be flawed reasoning because cryptocurrency in not controlled by the banks or institutions at lest not yet anyway. Which is what gives cryptocurrency it's basic value to by pass the banks. I believe our society will determine it value not the governments (like what is happening in Venezuela), not the banks and not even wall-street. Steem on baby Steem on!
Steem on baby!
I take "experts"advice with a grain of salt when it comes to crypto-currencies. It wouldn't make sense to even say that Bitcoin is in a bubble right now because it is still relatively unknown to most people. People were calling it a bubble when it hit 100 dollars, but what we have seen over the last few years is exponential growth.
