FOMO isn't that bad simply because it can leads you to be in profits sometimes but not every time so its more like how early you enter into the ship and exit at the perfect time before it gets drowned.But there is no other reasons to call it as good, and even you are manipulated so don't become someone who make decision for other's profits.
You accept risks and join FOMO parties. Good or bad it depends on each time you join FOMO party and how soon or late you join it. With FOMO parties, the later you join them, the higher risks of losses you will get. FOMO parties never last too long.
I disagree with this because you could definitely always buy at the bottom and sell it at the top but the challenge is when you will buy it. This should already be a common rule for everyone. If you check all the charts of the coins, there would always be a lower low and a higher high. What you would do as a trader is when you are going to trade, what indicators tell you to trade, limit positions, limit risks, and many more. It's not going to always be about FOMO, it's about being smart with what you are trading.
Buy the bottoms, sell the highs and make a schedule when you will make your sellings. Your plan and your patience will help you get profits if you buy at good price (should be at bottom). Sad to say, even if you buy at bottom, you still can get losses if you don't have enough patience and shake your weak hands before the days your investments turn to be profits.
