Ditto. A decentralized crypto could succeed in a few months - all good.
A dot com exchange should never grow that quickly. The only thing that gives an on line centralized exchange trustworthiness is the time that they have been in business without a hack. But even exchanges with 6 years under their belt are only due to be hacked.

I am out of them all. Only bitshares and only less than 1% of my holdings.
