It's because of many negative news about crypto.
TA Death Cross, Whales bailing, Despair in dumb FOMO money, ICO Scams, ICO ETH dumping, Asian Crypto Bans, Overleveraged crypto buyers being forced to sell, Tether, Negative stories on MSM, Tax related selling, Wallstreet bandits manipulation for downward gains...
I'm sure we will get a shock of a decline 5k or so on BTC soon
