Let's talk about the recent series of coins launched by Binance. Many of them are ALPHA airdrop coins. I can only say that while one can profit from airdrops, one should not be a bag holder. I also tried trading the contracts for these coins, and my gains and losses were basically balanced. You have to calculate carefully, at most I earned that 30% commission rebate. One logic to understand is that most of these coins are airdropped quantities. Those who profit from airdrops or studios emphasize liquidity and will unhesitatingly sell off their holdings to prepare for the next opportunity. Additionally, coins of this type won't have major market makers coming in anytime soon, so the liquidity is definitely poor, especially in low cycles. This means that when these coins get a favorable news boost, you won't be able to catch it. If you try to short, it will stay in a high fluctuation range, consuming your capital costs. I reviewed my trades, and almost all my profitable trades were when I chased in during declines, while my losing trades were swept out during high fluctuations. Another characteristic of these coins is that the holding limits are very low, which means that large investors with big capital will not participate; they are only used to cut retail investors.
