Investors’ greed has no break as long as there is demand in the market; the memes will continue to get hype. What makes memes in demand is that there is a market, promoters, and exchanges willing to support them; they don’t care about usability.
As long as there is an attractive narrative, promoters will hype it, whales will support it, and investors will sustain it. Memes are risky investments, but we have more types of investors who are willing to take the risks.
The greed has a stopping point and that is massive financial losses. Some people can't be taught a lesson any other way. You can warn them many times, you can show them examples but nothing works. Once they personally suffer massive losses in a memecoin scam at least once or even more times they will start learning their lesson.
