That is true that the main reason why people lose in trading is because they tend to use their emotions instead of looking for technical and fundamentals of trading. They tend to get afraid and scared every time they see that the market is falling but its a very wrong move I think.
This category includes trading beginners who do not have an ideal understanding of the crypto world, but they tend to take advantage of the bull run moment for instant profits, when the market correction conditions occur they will cut losses because they are unable to control emotions due to losses from short-term trades, that's the risk in trading if there is no knowledge then there should be a need for crypto trading analysis knowledge.
Because they don't fully understand how the market behaves, then their decision will eventually result in losses in the long run, riding when the market is in a bull run requires extra precaution as anyone could also dump due to the result of market manipulation.
So, anyone who has little knowledge that witnesses a big dump might easily panic thinking the bull run is over and the price will dump hard, they are thinking of taking advantage but in reality, they were the one who was taken advantage by the whales or the market manipulators.
