Carding is a very easy and simple job.
It is enough to connect vpn for these purposes.
It may seem difficult to work with sites on which anti-fraud protection is installed, which determines the carder, but such protection is not available on all sites.
Nevertheless, this is illegal work, if you have doubts, then it is better not to do it.
Stealing money from other people's cards is a bad idea. You have to think about your karma.
