Bitcoin flash crashed on Kraken exchange only from 37,500 to 35,000 back to 37,500 again in a millisecond.  This caused me to lose 8000usd when it triggered a stop loss at 36,200 and sold at 35,400.  No other exchanges experienced this flash crash.  I wish I could upload a picture of the graph.  Single second spike down and right back to 37,500.  I talked to a manager at Kraken and he said the exchange functioned as it should (of course).  Also, he blamed me and said I should have used stop limit instead of stop loss.  I had just purchased Bitcoin at 37,500 and was watching the graph go back up towards 38,000 when I put the stop loss order in.  I was estatic to that the price rose quickly to 38,500.  A couple minutes later when I checked my account I saw the stop loss was initiated (it never indicated it dropped below 37,500 on the graph I was watching on the app).  I feel I was cheated out by Kraken and lost thousands. Not sure what to do about this or if anything can be done.  Has anyone else experienced anything like this before?  Thank you in advance,  Joseph
