Day trading or short term trading is not for me at-least and there are much success stories. Even experienced day trader finds it hard to tackle Bitcoin and incur heavy loses. Its always best to invest in Bitcoin for long term since thats the most reliable way to invest in any trading market. Day trading can give you profit occasionally but in the long run you are deemed to lose.
Day trading is not a bad strategy to me anyways. Sometimes the error might be as a result of not having a proper trading plan. Trading plan covers a whole lot.
Some people trade without a solid plan of maybe day trading or swing trade. If you plan to day trade I think it's best done scalping the market to archive a particular target(inclusive in your trading plan) and after archiving that you close for the day.
Meanwhile swing trades you trade them and allow the trades to bring all what it gats regardless of the period of time it would last. Some people enter scalp trade entries and hope for a big and long term wins which latter bounces back and ends them in a loss. I'm also a victim of this but really trying to correct it though.
So know the one you belong and hold tight.
