I use my Trezor BTC address currently and recently it went Segwit aware.
Do I need to generate a new BTC address (Segwit) and update payment settings at kano.is ?
Thanks
Thus you will be able to spend the payout no matter which it is.
It's how you spend it that matters - so if you want to be able to spend it using a segwit type transaction, then it will need to be an address that can be used in a segwit type transaction, so you'll need to have a '3'/segwit address as your payout address, to do that.
