You need to do researches and pick coin you like and of course use several strategies for making more profit!
You do not need several strategies to trade, you only need to find one strategy you are comfortable with, build on it, practice it very well until you are confident enough it will give you desired result and then keep to it. How to trade does not mean how to get into trading but it really means how to trade profitably, again it is not dealing only with making profits but also dealing on how to avoid losses or time wasting trades.
The mistake a lot of traders always make is to keep trying to use different strategies at once, without getting to master one, and that sets in room for a lot of mistakes as far as I am concerned. In this case, you really do not know where you stand in any trade and you just keep making guesses based on the fact that you can’t stick with a strategy.
