Guys, my son is going to earn something here, he's asking for money. I technically registered myself to see what's going on here, I saw the forum and decided to ask decent people what’s going on here? I don't understand it myself, but I realize that there is a future in this thing and I don't want to ruin it for him. Let him play around, learn. Just tell me which direction to guide him and what to keep an eye on so he doesn't get disappointed. Thank you!
