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. 
What difference does it make if they treat bitcoin and ethereum as cash. Are they doing it so that the government could identify these transaction so that you will be able to pay the taxes for every transactions you make with the bank to any exchanges ?. Apart from these i do not see any milestone as i am bound to pay my tax if i am converting the bitcoin to cash and i was doing that for the past few years.
