Always wanting to catch the full market cycle, finally giving all the profits back to the market

A friend of mine, who has been trading coins for three years, knows a lot about the technology, and is good at analyzing charts, but he just can't shake his greed.
Every time he enters the market, he wants to buy at the lowest point and sell at the highest, always thinking about eating the entire wave from start to finish, not wanting to miss a single moment.
Recently, he started building a position in altcoins, entering at low levels and riding the wave up, with his paper profits already quite substantial.
I warned him at the time: the resistance level is reached, take some profits off the table first, don’t be greedy.

But he refused, always believing there’s still room for a bigger surge, fantasizing about doubling his gains and then leaving. As a result, the market suddenly plunged without warning, crashing downward.
What he had already gained was shrinking day by day, turning big profits into small ones, small profits into losses, and eventually getting caught.
The more he held on, the harder it was to let go, clinging to hope for a rebound, until he couldn’t bear it anymore, and had to cut his losses painfully, losing not only all his gains but also ending up in a loss.

He told me afterward with a very painful words: The most harmful thing in the crypto world isn’t not understanding the market, but knowing you’re making money and still being unwilling to be content.
The market will never indulge greed; if you want to take all the profits, the market will take everything back, including your principal and gains. Instead of trying to chase the top or bottom blindly, it’s better to only eat the fattest part of the fish, leaving the head and tail behind. Knowing when to take profits is more important than knowing how to buy.

Stop messing around! Master this position rhythm, even small gains can ride the main upward wave comfortably, follow Brother Li step by step. #BTC
