G here,
This morning I have sad news to bare.
This non-segwit onramp for the USA known as Coinbase might have a massive problem in their unlaying infrastructure
Block Digest's ShinobiMonkey Discusses how a Bitcoin Address claimed by a Coinbases customer with a total of 203 Bitcoins would be leaving dust UTXO's. This would be making the fee 5x times the amount needed to spend the 203 bitcoins at a hefty sum of 1006 Bitcoins!
Something is array in the Coinbase infrastructure with the amount of spend fee UTXO's pumping up the business model for coin base is looking grim
