Which systems are with less risk? It's interesting, because my mind is that only in a system which I control I can be sure.
Well, this makes the system the safest system for you. But for everyone else? So far you are paying and you have had enough good opportunities to run with a high amount of money. Nevertheless, I would not call it a safe investment when I have to trust your word. You are just an anonymous person in the internet from the point of view of everyone else.
