What rise of memecoins?
From early days when the altcoin market formed, there have been many useless coins created and sold to newbies. The market is not bigger but the principle is the same. They create garbage and sell it to anyone who buys it.
In fact I think people trust memecoins less than before, which is clear from the smaller pumps they get compared to for example 2017.
I would say people just understood the gist of them, so they don't come near them at all.
Those who didn't - they will learn it the hard way, probably.
But alas, the memes are engraved into the space. And are used by some in the degen trenches.
