if a bitcoin transaction using a username might be a lot cooler too, I might be able to think positively in this way the transaction would seem to be great if some coinabse users often make small amounts of transactions using bitcoin, so it doesn't pile up on the bitcoin transaction network, but I say before this it still didn't look great if it was done only for coinbase users
he has been fighting for this patent since 2015, so it's natural that many use something similar every year. If coinbase wins this patent, it means that all other services can still use it, but by following the fixed rules of coinbase.
I still think this is no different from the branch address system, but I don't know the details. What is clear is this feature will benefit users even though they can no longer avoid KYC etc.
