Despite the fact that I think bitcoin is a bubble - it does not stop me from selling it. In addition, I'm sure that this bubble will have an incredible future.
I think the high price of bitcoin is not a bubble, the price of bitcoin is created because of the large demand for bitcoin while the offer is little, finally this inequality makes the price of bitcoin soaring. But it's not a bubble, because if the price of a bitcoin is bubble that means it is pumped continuously to the maximum extent, after that it breaks into no price. Bitcoin is not like that, there is a decline but it's a fluctuation due to supply and demand.
