Hi,
Now it is crystal clear that last year rise was purely caused by manipulation (= FAKE DEMAND)
For all those hoping that bitcoin will become mainstream, then those times are not for today, sadly.
My humble opinion is that bitcoin could get adopted by the mass but only in the very long term (circa 10 years), in countries such as Japan. So this will take a WHILE, and of course any government decision can harm bitcoin. Japan is friendly towards bitcoin, lets hope it remains as such in the future.
I do not really think you follow the trend of cryptocurrency event last year. The massive appreciation in price of bitcoin last year was due to the several bitcoin fork. When people realize that some percentage of the newly fork coin will be given to them if they have bitcoin in the right wallet or exchange, people started investing massively.
