Thanks,
I meant same process, If I could directly transfer the BTC back to Kraken without any other online wallet, just import my paper wallet address from Kraken.
I do not know if it is possible to import your own private key to kraken. Probably not, but there are some exchanges that allow that.
Easiest solution is to install eg. copay to your mobile phone and scan your private key with that, and then send the
BTC to wherever you want without any fees except miners fee ofcourse...
