About firms and brokers

Hey everyone, I am 22 old and live in Russia. Trade around 3 years and now I start make profit. Where I can trade CFD without fear for deposit. Now I trade on Vantage, think about step up broker seriously. I don’t think vantage is bad broker but his no have regular system. Maybe I need to move to America to become a resident and sign up with a major broker? Or u now other brokers with good reputation? (Not registered in USA)
