For the main work with the tool, you can understand a lot of what knowledge you have, just like you can find carding on this forum, there is a lot of the lowest and easiest level in carding, it's weight carding (Hint: all manuals and books are on this forum).
But specify that everywhere you need funds to start (materials for purchase), and you will also need a drop and a purchase, you can see liquid goods in the manuals (I remind you: here you can find everything that is necessary, including proven sellers)
But you won't be able to work if you don't have basic knowledge in this matter. So you can start your development and learn it.
There is also coding, you can become a professional coder and write malware, scripts, useful software. But for this it is necessary to know language programming (python is enough), but it is difficult and difficult, but if you study, then in a year, or maybe earlier, you will start earning good money and creating your own projects.
Good luck in your beginning!
