I really like crypto cards because they are pretty convenient because currency bitcoin to fiat process is too much lengthy first we need to send our bitcoin from binance to central exchange like coinbase after they take some time to send in bank accounts so if we have cards like bitpay so this process will take only a few steps and few time we need to send bitcoin to bitpay wallet that it very easy also bitpay takes 1% bitcoin to fiat conversation fees while local crypto exchanges takes more than 4%
Bitpay must implement their business on the whole world because currently so many counties available there no credit or debit card service available
Bitpay currently support bitcoin and bitcoin cash, but I think they must accept significant currencies like ethereum ripple and many other significant cryptocurrencies
