Buy a VCC from someone who supports whatever you want (Bing,Facebook,Google ads, etc) and then look up its bin number. VCCs are this whole secret business or whatever but the reality is that a ton of VCCs aren't actually VCCs. Many are just bank cards in other countries that haven't been blocked yet or obscure prepaid cards.
A lot of the BTC payment VCCs are down right now thanks to an issue with Visa. They all technically came from the same place.
