Bitpay are heading down a dead end with their continued disdain for BTC. It's only a matter of time before someone pops along who is actually interested in doing business rather than fulfilling Bitmain's doomed agenda.
They probably realized their whole business model is untenable. If Bitcoin/cryptocurrency actually sees mass adoption, nobody needs a payment processor. And what is that, 10 years out? Maybe less? They'll be looking like Pets.com. I assume that's why they only care about the immediate future (big blocks/cheap fees now).
