It's crazy actually, my story is very similar to yours. And I read about so many other experiences that are like that : you start successful, then FOMO hits hard and you lose so much because of it.
I read about TRX in another forum and bought it when it was tooooo expensive. But hey, everybody was saying "it will go to the moon" so I believed in that. Long story short: I sold it too cheap and lost a good amount of money.
Recently read something about cut - loss strategy and I think this is very smart. Know your boundaries.
