Trials are based with minimal amount, once you get the hang of it, you will know when to go all out and when to stop but even at that, you still need guidance from key points, is a bit complicated, especially when you want to do it full time but it can be rewarding
Always trade early with either demo accounts if you can find them or a small amount of money, as trading is very rewarding but is also quite risky, and you really have to get the hang of not letting your emotions get the best of you. Also make sure you've got good data, follow the news and flow of the market, the app from coinalert does a pretty solid job of bringing it all in 1 area to monitor the markets your targetting too
