If mainstream currencies such as Bitcoin, Ethereum, AAVE, and SOL are not harvested. There is a high probability that you don't need to pay attention to other altcoins. The cryptocurrency market itself is not yet mature, and most of the time the trend of the currency still depends on Bitcoin. Occasionally, counterfeit coins emerge from independent market trends, mostly selling at high prices, and accidentally becoming buyers. Instead of blindly casting a net, it's better to focus on making mainstream strong coins, which will result in much higher efficiency and risk return ratio.
