My experience on Kraken yesterday: I knew the btc price would eventually crash, I was waiting for it. Once the fall begun, I went exchanging my btc for eth which is more stable.
I had to frenetically hit place order for 10 minutes to get through. I ended up with a double order, whereas the price was already very low... I see it's rising again, so I go to change my Eth for Btc again, same thing happening: 5 minutes to go through the order. Result: I sold low, and bought high. 500 Euros of loss in total (including the fees of transaction), which should have been a profit of 1000 Euros if worked as intended.

This is a joke.

With the money they make I don't understand how can their servers be soooo bad ? This doesn't make sense.
