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.
Yes, short trading is always better when the market is fluctuating because the prices may drop suddenly it will lead to losing huge amount of money. Day trading will be much beneficial to those people who have a huge amount of money because they will easily manipulate the market and makes them a huge amount of money.
