now the problem here is that a bot is not something that should be used by everyone! specially when they are new to trading itself. ignoring this fact a lot of them buy bots because they think it is magically going to make them profit. then failing to make any money and losing more that they even imagined they decide to sell their license. for that they exaggerate the capabilities of a bot and bring in even more newbies who think they have bought a magical tool that can make them rich.
after a short while we are left with a market filled with a lot of people trying to resell their license to make up small part of what they have lost so far.
