The FOMOs are trying to get rich overnight, but ended up loosing everything. I wish people get it that only trading / investing in Bitcoin will bring you profit. It is not just the shady altcoins. This can happen to bitcoin as well. Remember in 2017 when noobs FOMO when the price of bitcoin is at ATH in 20K. Then all of them dumped when the price started correcting. They all lost because they FOMO without basic knowledge of bitcoin or cryptocurrency.
If you are a trader, you do not need to stick on bitcoin alone. What is important is that you know what you are getting into. Both bitcoin and altcoin are profitable as long as you do not fall into traps, you understand your market and you researched and have full knowledge on the coins you are betting on.
