Hey guys!

Im a bit new to monero, have a decent cpu that isnt doing anything so i thought id put it to work! However kraken (easy to start with since i already haven an account there) doesnt seem to give any payment ID. What should i fill in under "YOUR_PAYMENT_ID" or should i just leave it blank?
