I think that yesterday was a panic selling by some people because the china government has tried (or did) affected the bitcoin by tried to control it, but the price again went a little up.
I do not think that yesterday's events and fluctuations in the price of Bitcoin is just a panic. Surely there are some hidden reasons
The reason behing the panic is that there are rumors that the chinese government will implement some strict rules against bitcoin and they would start taxing them heavily in order to reduce the amount of money flowing out of the country and this news had a big impact in the price
I think if panic seling the case then I think it would make to lower prices, but today you can see that the price rise is very fast, and of course it's because of panic buying occurred. I do not know the reason why panic buying this happened but the important thing is panic buying will always give a nice effect for the price of bitcoin
