I could not understand what is happening, from price correction to this mighty price dump. Bitcoin bellow $3500, ethereum $235, litecoin now $48 and ripple fall below $0.19. I think Chinese government and traders are really dealing with altcoins and bitcoin hard now.
Bitcoin trading has been banned in China, major exchanges will cease operations, people are cashing out while they can.
Everything will go down.

Probably exchanges will wait for regulations and resume trading after few weeks/months.
They will still trade until end of September. Maybe by that time, they will be regulated and continue trade afterwards.
