I've tried trading a few times...And ALWAYS the better and more profitable way is to buy BTC and HODL.
If you want to try to do trading, the first step is to have a Trading Plan, where you have on paper under what circumstances (volumen, pattern, type of candle, MACD, etc, etc, etc) you buy / sell and the % of your capital you're putting on risk.
Once you have it on paper, its time to do a backtesting (2 years at least), find the data from the past and test your system.
If you get good results (define good, 20% profit, 50% profit?), then you can try your system with REAL DATA but with fake money....If you are profitable, you're ready to go for it.
Its not an easy path
