Is there any reason why the btc price is dropping again? Im keep checking the news and i cant find anything which could be the reason of a 200+ drop in the last day...
Also, it looks like the bitcoin is always dropping fridays / over the weekend?
Has nothing to do with weekends. It's just normal market activity and perhaps a bit of panic selling from traders that believed in the rumors that the Chinese government was going to ban miners and the bitcoin network after they ban the exchanges.
It's not a big drop, only like $200 or so.
I don't think you should worry about it too much. Price should recover at least to $3800 if not $4000 or more(would require some strong bullish market, though) by the end of the month.
