Guys, I think it was a short Binance, apparently they may have released their influence, seeing Tensorcharts.com the graphic:

In the 1D sail, see "Shorts" and sale of 20,744.75Btc, and purchases at the same time of 15,181.07BTC, I highlighted in yellow in the box.
Then when seeing in Bitfinex:

There were equal Shorts but with sales of 5,436.11 BTC, and Purchases of: 4,662.27BTC.
And when reviewing the "Shorts" by TradingView:

The "Shorts" are still open
It is necessary to wait for the positions to close, but it is seen that there is a fight of bulls and bears, what there were are "Shorts"
I think you should not panic, because they made "Shorts" and did not find much offer, maybe they are testing that area, always to buy, the smartest is lowering prices.
