I am not familiar with a good payment solution for crypto let alone for Hive/hbd

Coinbase is said to be easy but it doesn't have hive. Binance has credit card support but is not usable for US residents and many credit cards don't allow crypto transactions and will reject binance (like my own credit card)

Maybe PayPal has something.

And I am just not familiar with the two you have referenced so if you think they will be simple to use send links or tell them to get a hold of us
