No problem. It’s always never too late to learn, however, like @Hyperdemongod said, you need to fiddle around a bit and look things up yourself. There are a lot of other forums on the internet, but 1Hack being one of the kindest, here, you’ll most definitely find people always ready to help. That being said, showing a bit of initiative and getting excited about doing something might inspire you to probe deeply to the level needed for patience and understanding in carding or cracking in general. Additionally, spamming the same questions is not a wise thing, it’d be better next time if you used the PM button - I’ll be happy to help out.
Anyhow, coming to your question, here’s a past post where you’ll find precious resources and links to help you deep dive into this topic - https://onehack.st/t/solved-what-are-bins/73703
Cheers and Good Luck!
