While the technical side of grabbing cards isn’t incredibly difficult, getting a bot to play a decent game is a more difficult challenge. Remember, unless your bot is capable of winning in the long run then all its going to do is automatically lose your money. There’s few stories of bot players making millions and plenty of players’ bots getting detected and forfeiting their funds as a result. It may be that the only people making money are those who sell bot software. I’d be interested to hear from anyone running a profitable bot.
