I always tell myself I’m gonna stick to a monthly Bitcoin buy… and then life happens. One month I forget, another month I wait for a dip that never comes, then I FOMO in after a pump and screw the whole strategy.
You don't seem to understand the fact that the moment you specifically choose to apply DCA you are simultaneously ignoring any form of FOMO. The idea is to set a constant amount mostly every week and keep up consistently with it. You got this wrong by investing a huge amount (based on your income).
If you actually want to DCA you'll have to stick with an amount you are capable of risking ( that's where the phrase invest what you can afford to lose comes in).
