Something to take into consideration are the tax implications. Now I don't know where you live, but in the United States, day trading results in a higher tax rate than those than hold an asset for longer than a year. Therefore, if you're day trading, you need to factor taxes into how much you'd have to make before you actually reached break even and then started to make a profit. Further, for tiny movements, you really need giant amounts of an asset to make any real money. That's why we see bots buying/selling thousands of bitcoin at a time. Only then does it become potentially lucrative.
that's true for day trading bitcoin too.
