The rewards for the second week of the contract trading competition were credited yesterday, totaling 3,500 yuan in cash. I didn't do much research, so I randomly chose 13 coins to try my luck. I entered on Saturday, and now the account only has 1,700 yuan left, a significant loss. To be honest, in this market it's just gambling with luck, always hoping to encounter that tenfold, hundredfold, or even ten-thousand-fold coin to take off directly. Should I continue holding these 13 coins or not? It all depends on luck and market conditions. Mainstream coins like Bitcoin and Ethereum are more stable, but sometimes the potential of small coins is truly unpredictable. Just consider it as paying tuition fees for learning.
