Unless Im misunderstanding what was said here, I think there is incentive in keeping your coins on Coinbase system (unless they get hacked and you lose everything but hey, thats why they pay CISO guy big bucks!! :) )
From staking that you can get now for coins like Tezos and I think others as well, also for when coin forks like BCH did, so you get bunch of BSV coins for doing nothing just for holding BCH coins.
