Trabalho com investimentos, vejo isso todos os dias com meus clientes chorando por conta disso.

Number One Mistake New Crypto Traders Make.
One of the biggest mistakes new crypto traders make is not taking profits when the market is bullish. It’s easy to get caught up in the excitement when prices rise, especially after a long period of decline.
The market may have already risen 2-3x from its bottom, and although it is tempting to ride the wave, many traders neglect taking profits when they are sitting on a substantial gain.
This often leads to missed opportunities and the painful scenario of watching those profits evaporate when the market eventually corrects.
