But, what did he exactly said? any links to interview or something?
If he said that Bitcoin will not survive, he cannot be sure. If he is meaning that governments would not allow it, well maybe they will not like it much, but neither do they like file sharing and it is still here.
This is what he is saying ....

JPMorgan dish it out. You would also try to protect the hand that feeds you. The IRS ruled that Bitcoin is a commodity and then the government turn around and auction off bitcoins
for cash. In the end the voters will have the last say, or the banks with the biggest pockets funding the election campaigns.
