BTC is continuing it's sideways trend frustrating short sellers waiting for the big plunge back to a thousand. I do not believe this will happen as Segwit2x will shake out and possibly hardfork into two chains. This means a split, at 2500 BTC Core is worth 1250, the other also 1250.. dominant chain? Who knows? New target prices are 3500 short term (6 weeks), and 4300 in nine weeks.
If you do go short, use extreme caution and a reputable broker.
Do your own research, and consult a professional financial advisor.
