I don't think so.
As you all know, crypt currency is not safety and equal. 
Of course block chain is safety, but there is someone who control it.(Miner, Exchange, Rich Investor.)
As long as people handle something of crypt currency, problems happen.

It must be completely neutral.(Not 100 percent.)
I guess crypt currency issued by central bank of each country will be the future of money.

I think it is bubble.
But after breaking bubble, the real demand of crypt currency appeared.
Its gonna be stable or increased little by little.
And competition of crypt currency will be more intense.
