I already know that. However we need to be able to buy things with our crypto, and BitPay is among the most widespread thing used by businesses for them to accept crypto. We just have to deal with them not accepting Litecoin but accepting Bitcoin Cash. Both are faster with low fees, and we need a majorly-accepted currency that's fast with low fees, which Litecoin was I believe the first to be that.
But now there's Bitcoin Cash, which is already worth more based on marketcap than Litecoin. There are actually many other coins that Litecoin has to compete with. And BitPay and all the businesses that use it can accept Bitcoin Cash now, not Litecoin.
