You can still trade, but most brokers will require a compliance letter from your financial institution proving that it's OK for you to trade -- and thta you will only be trading your money, not the bank's clients' cash ;)
I like how I signed in to read this thread and there is an ad for the Russian Alpari brokerage on the top right (for me, at least)... ha, I can't believe they're targeting U.S. clients now... are they outta their minds? Which normal U.S. client would ever chose a Russian broker in their sane mind?
Doubling money is easy: start with $10, make $10 more by getting 1 tick in futures (minus commission) and you have $20... then again, most brokers won't allow you to start with only $10, lol.
Trading is not the same as gambling... a dumbass can make money gambling on a fluke, but to be a profitable trader long-term it's not a one- or two-time thing... you actually have to have a tested strategy and execute it well. In short, you gotta know what you're doing... Definitely this is much...
