RE: Do you think an economic crisis is coming?

I do agree with you there.
However, on the other hand, i would ask differently: have crisis ever stopped? Nop, and not meant to do so at all. It is a cycle in which each time someone who has it "under control" uses it to "makes money".
But whether the Crypto-currencies are the solution fingers crossed. The market cap for crypto is still too small to substitute the dollar, yet ;). At least it is decentralised so nobody will start a war against a dollar competition.

ahh economics....
