1. The Chinese government prohibits all websites offering cryptocurrency trading services, and considers closing all local exchanges there.

4. Sales with a large-scale sale method.
5. Speculation of losses at the Crypto market.
6. Regulatory changes to the Crypto market.
7. Increasing hacking cases, losing coins, and decreasing investor confidence.
However, there is certainly the possibility of other factors. Please add if you know it.
I suppose you are right about points expressed in 1, 3, while some others can be doubtful. For instance, problems with hacks occurred before and I am not sure that there are really more hacks now than there used to be. I am also not sure I understand what you mean by #4. Is it about the whales manipulating the market? And what are speculation losses? Could you elaborate more on this topic? Regulations are still on their early stage and I am not sure that it affects the price right now.
As for Google ban, it was one of the big reasons before, but the news is old now, so I don't think it affects the current situation.
I agree with Iyeman, that you should add to the list the point about SEC declining ETF applications. There've been three major price drops over the last two months related to this issue. And SEC might continue to affect the market, since new applications are filed and new rejections are most likely on their way.
