Bitfinex is notorious for this. This is why I don't trade with Stop Losses. I have seen the high spike on Bitfinex practically match my stop loss before trending back down and never revisiting the price point since. Ended up being robbed out of what would have been a rather decent short trade. That was my last short for a few week until I got in at $626 just before crash.
Stop losses do that when you place them at the same spot as everyone else. Try exploiting these stop cascades by strategically placed limit orders just beyond where all the stops are. That way you will enter with edge every time. When I started doing this I realized the stop cascade points where actually where the trends turn, you will mostly be on the right side doing this. And since you get in with edge, you can mostly scratch the other times.
