Do you know why FOMO is sometimes good?
It makes you more discipline, committed and patient.
The times you've entered earlier/later tell you to take more time and not to trade with heart.
The times you said "I wish" teach you to learn from the past and apply in the future.
I had 0.2 BNB and planned to double it in the next months, I did what wasn't expected.
Had FOMO and converted to USDT not to lose my funds.
I may say it may be impossible for BNB to get back to $270 level, maybe in the next bear market.
In conclusion, take more your time and plan ahead, trade with risk management.
