I can suggest for short trading instead of day trading. Because market is very fluctuate so that day trading is very dangerous for crypto traders i think. but if you go for short trading you can realize market condition and can take time for next step that you can not get day trading. so be careful about day trading.
It seems to me that you have slightly changed the concepts of day and short trading. The fact is that day trading in cryptocurrency is short trading on the exchange throughout the day. and long-term trading is cryptocurrency trading for a longer time. and based on this, each trader has his own way to these types of trading. for me, day trading is safer and more profitable, because I can always have time to adjust my actions based on the indicators of the cryptocurrency market, in contrast to long-term trading, when the cryptocurrency market can change indicators more than once during the day.
