Firstly, I think trading crypto is harder than any other kind of trading. It is so volatile, has no fundamentals or history. Alt coins get pushed around by whales. Trading FX/commodities is better - but chuck away the intraday - use day chart (maybe 4hr for entry) - and save yourself heartache and start by trading with the trend. Personally, prefer stocks but have more success with ETF's. If you interested in FX you can open micro accounts with XM.com, plus have great signing on bonuses. Have had no issues with them - been with them for around 2 years. Not sure why you need to pay for a course - a basic TA book to give you some structure, then youtube/ forums/twitter. You first hurdle will be finding a system/style that suites you - it takes a while, try not let is cost too much! Anyway, good luck.
