I was looking at that 4100 area to on kraken and wondering if it was going to bounce back that high.. Here's the issue with Kraken, it trades USD instead of USDT and because it also trades USD/USDT pair, its BTC chart is often off from other exchanges by $100-$200 .. and other times when USD/USDT pair is almost par, then the price of BTC is closer to that of other exchanges.. So this actually throws off the chart.. So I don't know what to tell you, it might get back to 4100s much later than you hope.. like perhaps not on this bounce.. hard to know when there are other forces at play.
