Vocabulary of the day, this is my first time learning that word. Well it looks like it suits the phrase we have FOMO which is fear of missing out, right now I feel JOMO since I was planning to short on BTC but slept and forgot to open up a short trade but now it pumps to $41k and now I feel Joy in missing out and happy that I didn't open a trade yesterday my position probably liquidated by now.
This is a good analysis of JOMO as I understand with OP but as I trader, you have no need of JOMO because you will soon take a wrong decision that will trap you inside it and depending on how deep you fall, you may get out faster or sink further. Every time in trading we experience both JOMO or FOMO. This is certain to be so with our trading.
