People say that Bitcoin should increase the protocol to include a yield like staking.
Then it wouldn't be POW anymore.
Although this feature is possible for some exchanges like Kraken. The interest would be around 0.25% PA. And the other website that I've seen is the interest accounts for Blockchain.com.
But you don't hold your bitcoins for the period of time you'll dedicate for those websites. Even with those percentages of profit, I'd be happy to hold it than to allow them hold it for me.
