Many people lose money on altcoins because they are not clear about its underlying logic. Shanzhai can only be done in specific market conditions and cycles, but most people start with the idea of making quick money through it, only to be repeatedly harvested. To put it simply, shanzhai can only be done once or twice a year, picking high odds opportunities at the daily level, otherwise it's better not to touch them. The more you want to trade frequently, the easier it is to have a completely wrong rhythm and end up being carried away by your own emotions.
