Do you guys think that bitmex exchange effects on bitcoin price? Because last year there was no exchange like bitmex. Now people are making money by short trade. Do you think it effects bitcoin price because exchange has big volume.
Actually, Bitmex has been around since 2014. It did gain a lot of prominence last year, but it's been a notable broker for years. Before Bitmex starting dominating the futures market, OKcoin, and to a lesser extent BitVC were the biggest futures exchanges. And before OKcoin rose to prominence, Bitfinex was the best place to short the market, going back to 2013. As you can see, leveraged shorting has already been common for several years in Bitcoin.
It seems like you're implying that short trading is driving the price down. This can be true, but only for limited periods of time. Shorters eventually need to buy back to close their positions, so they aren't a net negative factor for the price. Margin trading can create more volatility (including downside volatility), but it probably doesn't dictate the overall price trend.
