No, they are not cowards, when someone invests in crypto in small amounts, we cannot conclude that they are cowards. Just say, that's the amount they are willing to lose, Isn't it always said that "Never invest more than you are willing to lose"
In the bitcoin business, analysis is an important factor, but stable emotions are the most important factor. Bitcoin prices tend to fluctuate all the time, prices up and down are not strange. So you can't be a coward because prices go down, fear and sell all the bitcoin that you have. It's not a profit, but a loss. Then the bitcoin business shouted, which was not good, and became a coward because of his own stupidity.
