So far so good with Coinbase. But they will temporarily stop accepting deposit on Aug 1 and I am not sure when it will resume. I just wonder where the rejected payout goes.
I have no idea where it goes.
But if your going to change your payout address you should do it soon. Kano payouts go to the address of record when that block was found and not necessarily the address you changed to. So there could be some lag after the address switch.
