Reportedly US Banks are going the treat Bitcoin (BTC), Ethereum (ETH), and all crypto purchases same as Cash. In the crypto economy, this move is going to be a milestone. 
The milestone may not have anything to do with it but I think Bank of America is now considering BTC and ETH as cash although the crypto economy is improving the United States is generally taking such steps to centralize. Then they will be able to collect taxes from here But they can never break the decentralized crypto.
