Yes, you can start with small amounts. It would be best to look for a registered broker with a real government regulatory body behind it that enforces the law. If It licensed in Caribean, I would be wary. Look for European countries under The European Securities and Markets Authority (ESMA), Australian, Canadian, and U.S forex brokers should be just fine. The look for brokers that trade Micro accounts. These are smaller accounts that trade 1,000 units of currency, and trade small, figure out what works for you and go for it.
