governments are so much banning bitcoin lately, as much as finally beginning to regulate it. this was inevitable folks, and we got here a lot faster by attracting attention to ourselves, via the ICOs, and the wild bubble. At these price levels, capital flight just isnt the only issue; you can greatly facilitate money laundering with cryptos. the ico circuit has almost certainly accepted some dirty money; which has gotten washed into the crowdfund, and came back as shiny new tokens.
this doesnt necessarily have to be an intentional thing, but it is definitely happening.
