You were clear with out mentioning you didn't use VPN with Stealths. I called it roulette because if it's working on some VPN it isn't guaranteed. It isn't worth buying virtual cards for use with a VPN if the seller's saying don't use VPN's.
Wasn't I clear enough? Why would you call it a waste of time or roulette? If it works well, if not then you're not using a VPN and the matter is quite clear. In addition, there are many services that offer virtual cards for crypto, Stealths is not the only one.
