I call this type of coin meme coin, and I choose to invest in meme coin with strong community support. The most important is that the holding time can not be long, generally not more than a month. You sell it before it crashes, usually when it’s going up. At that time you will be reluctant to part with it, because you think it can rise again. But, in my experience, when you get a lot of referrals, it’s time to step down.
