Sad fact that new traders think trade is only buy and sell and hold. When coins that they hold not give good value for long time, they don't have any other strategies to get out from loss then make decision to cut loss and retired from trading.
well, it's natural when they think like that. basically, trading does look like buying and selling. however, they did it with their will. the most important thing about it is finding information before trading. without doing that, of course panic sell will occur.
People who panic normally loss, we have a lot of traders and investors in crypto but there are some who just invest to loss their money.
They enter in the market without making a research, that's why they loss, they are newbie who think that making money in crypto is easy and can give quick returns.
We can't be panic if we got the acquired knowledge, and for us to have it you should focus on building your self confidence. Having research was just a part of growing as a trader, but if you're too agressive to meet all your visions in life you had more possibilities to lose along the way. Panic is a result of lacking of self trust, that's why after such wrong decisions made you tend to sell earlier rather than holding longer to achieve price growth.
