Its a double edged sword we are dealing with, China creates the popular need for crypto because of the damage done to their FIAT currency by government control and lack of capitalism.  So you have demand thanks to communism for alternates, now you have the other end they also want to damage any alternates as this reduces their power over their peoples own hard earned assets.   The main thing is there is still going to be a large amount of demand, they wont unwind the harm already done to their currency and this makes the base line for crypto still good I think.      There is already market competition of course and gold and all sorts of other ways to transport value so this is just the fight that has to occur.

Purely on the graph the bigger line we had held for Blk pricing that related to spring 2017 strength, this line was dropped below which makes it then weaker in action that appears.   It happens in time with general BTC weakness of course, the next line of possible support would match highs of Jan roughly I think just looking very quickly
