Not really, I don't think so. First of all, you need to trade on a demo account with this broker, especially if you see this company for the first time.
That will save you from unnecessary money spendings in case this broker won't fit you.

Of course not! It's enough to save a little money that you can put in your account and start trading. But I recommend to observe the risks in order not to lose even a small amount of money.
