I don't know why all these projects are launching tokens, maybe just to get more money
Well, you answered your own question pretty fast and nice!
There is a constant overflow of both chains and sidechain and layer right now, oversupply with limited userbase, and, that's all.
Also rebranding of failed projects (in this case AAV) is just...meh!
Buy a few early, dump with profit, next cycle next coin, layers2 are popping like and right now, probably a sign the meme hype is dying and we need another one!
