this has nothing to do with bitcoin or its price, it is regulation and it should have happened a long time ago, it is just bad timing. and it has been happening in the US and now it is happening in China and will continue in other countries.
whenever you do a business in any country and handle lots of money you have to be regulated and have license that is not a new thing and not a bitcoin thing either.
the fact that bitcoin price is going down is because there are many whales who take this opportunity to make a lot of money from weak hands.
