I saw someone talk about SUI but I didn't buy any of them because I don't trust MEME coins much. Those coins will get pumped and dumped like crazy as people make money. So it's hard to really know what decision is right, but at least it's a small position for you.
Theoretically, it's not a meme coin. It's a standalone L1 chain, with its own ecosystem of projects (some of them, memes). But it is a chain inspired from the culture of a centralized entity like Meta, embraced by Wallstreet people and VCs, so I have little hope for it as a "valid" contributor to the crypto space, in my book.
