The Joy of Missing Out (JOMO) renders a bad trade or missed trading opportunity as irrelevant, because there will always be another better opportunity to enter the market.
While the fear of missing out (FOMO) is the opposite of JOMO and it is a psychological state that is caused by fear and greed. It makes a trader abandon their plan often at the worst possible time to join another trend.
These narrative of both JOMO and FOMO seem to add up but for the full scale of your post, you seem to be missing the explanation rightly for me at least with the way I understand them, if JOMO is Joy Of Missing Out, that means an intended investment would have gone bad and the would be trader or investor is happy not buying. So probably the coin was pumping but the trader decided to be patient and watch the move then suddenly the rug was pulled off the foot of investors, hodlers or traders (if you understand what I mean) and the crash happened. In such case JOMO happened, Joy of Missing Out of bad investment. In the other hand, FOMO being Fear of Losing Out is basically what we know as being in a haste to rush in and in fact going in at all cost "to avoid" losing out on the profit but this as have been said, can be profit or loss at the end of it.
So if you buy a coin in a haste because you don't want to miss out, you FOMO and JOMO when the suppose good investment didn't go that positive way.
