Sometimes it's better to just hold a bunch of good coins for months than daytrade (because you can miss huge pump).
Day trade is better in many cases but it actually varies person to person.

Then calculating the percentages and ratios for your profits and losses. If you can manage such tiresome routine, brother you are made for day trading.
