In 2021, I continuously selected 10 projects in the primary market, each testing the waters with 100u, and all ended up losing badly. Some ran away, some surged tenfold without selling, then plummeted without ever being listed on an exchange. Some went directly to small exchanges that don't accept mainland regulations and block IPs. So later, I stopped expecting to gamble for a hundred or a thousand times return, and instead, I honestly focused on the secondary market, strictly adhering to trading discipline, more like trading stocks 24 hours a day. Fortunately, there are limit orders, automatic take profit and stop loss, and even if I miss a sell opportunity, I don't feel regret, I still follow my trading strategy. For new coins, I generally only use a very small position to play around, to the extent that if I lost all that money, I wouldn't be too heartbroken; this scale varies for everyone. There’s no concept of stop loss when playing new coins, only taking profits and withdrawing part of the principal to continue trading. Otherwise, it would be better to just place low limit orders to buy mainstream coins directly.
