Bitpay is a way to pay your bill in Crypto and one of the biggest companies. They may have a way to change to fiat but that's not the original purpose.
Wrong again, Sir. Bitpay was created to allow businesses to accept bitcoin, but get the exact amount in fiat. That was their original purpose and even says so in the name.
If I have BCH and I go pay my bill in with Bitpay at Dish Network I don't have to change anything to fiat. The business has the option of changing to fiat or not.
Then what will their business model be? ABC supports a securities platform. Problem is, securities already destroyed Ethereum and they will destroy ABCs coin.
...and the verdict is still out on whether ETH is really "destroyed". That notion is a bit premature when someone knows just a little bit of crypto history.
