Many seasoned and less experienced traders have made fortunes through trading on Bitcoin, stocks and other tradable assets. At the same time, many have suffered huge losses, so whether investing real funds into trading is worth your while will eventually be judged by the outcome of your trading endeavor and thus nobody can give you a definite answer. What is certain however, is that trading is always risky and not an easy task, especially if you trade with your emotions and hear and not with a cool head. Simulators are important in this regard, as they allow you to try out different trading techniques and learn and improve your trading skills without risking to lose any of your capital.
