Is there a decent alternative for Bitpay?
There are other payment processors like Coinpayments:
https://www.coinpayments.net/which accept alts.
Bitpay's problem is that it is bitcoin only and they never imagined that the mempool backlogs could get so big and thus didn't have processes in place to deal with that.
Hopefully Bitpay will see the light and enable alts.
