It was fine for me, but a friend just had her account suspended and was told to sell all her BTC (which will incur a substantial loss). There is not evidence for why they are doing it. But they dont even allow users to withdraw the BTC they bought - they force liquidation, even at a loss. This is a scam by Kraken - basically they take the spread first selling BTC and then forcibly making users sell it back. I will be closing my own account and using a more reliable exchange in future - one which doesnt scam or steal from its clients.
