Instead of this, why not make the fees part of withdrawal to be editable so the sender can choose what kind of fees to set. That way, every user can own their destiny. I mean, that way, every sender can reduce block time from what it is currently. For some time to come, we are still going to have congestion and high fees, no need wishing it away, but you can fix this by allowing people fix the fees they want to pay not imposing one and making it a luxury service. Is that too much to ask? For a customer centric business like yours? I mean, you should be able to put the customers first like you always strive to do. A good service is always about improvement and customer feedback and I don't need to be told that this issue would make up the no 1 complaint. Withdrawals too slow!
