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. 
I think you are referring to this article.
Bank of America could treat transactions with Bitcoin as cash
just add it in the OP so everyone will see, it's nice if you will put a link of information you shared so we can verify, and so you will not punished by violating the forum rules which is plagiarism.
The OP's title is misleading as there is no ETH in the article although it is said that cryptocurrency in general is accepted.
Now with regards to the milestone thing, it will be a good thing for crypto as a whole but the chances of this to happen is relatively low and the article site isn't as reputable as other trusted sites out there so I don't believe that this will happen or should I say I'm not expecting for this to happen though.
I'm not gonna buy this either there are so many news coming just to create a hype so maybe this is another attempt, I want to see this news on biggest crypto media so that we can verify it that it's really happening in certain bank. But I'm sure many want that to happen since it's another level of adoption and people can gain trust with that thing since imagine the banking institution use that for good transactions.
