I learned about this word today too. It stands for 'Joy Of Missing Out".
You were thinking of buying a coin and later that coin dumps to oblivion. That's JOMO!
I've experienced it several times. and even that became a nightmare for me. but I just found out that this term is JOMO.
I just recently bought a token called MetaSims on the Bsc network.
chart looks healthy for some time even looks very positive. and I decided to buy it. but when I wake up in the morning. I was surprised to see the prices have fallen completely.
maybe someone else is buying this token here.
really very annoying and frustrating. because the project looks good and there is no sign the price will be rugfull
