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.
Maybe it used to, but I don't think it does anymore. Back in this summer bitmex was a viable option to short bitcoin and hope the price was low and people with money sold all their coins to keep the bitcoin low and recollected at the low amounts slowly. When you buy 10 bitcoin a day you do not change the price but when you sell 200 bitcoins all at once you drop it lower.
Which means people kept buying bitcoin slowly and sold at once to keep the price low and make money from their short positions in bitmex. However if you check the volume right now it is clear that no one can do such thing or has done anything like that for a long time, price has been stable and the volume has been stable too and there has been no "sudden sell" that caused a stirr up anytime in the past 3 months.
