Depends on what you mean by “best investment.”
If you’re talking about high-risk, high-reward coins, then maybe memecoins fit that. But overall, I don’t think the memecoin market is really profitable, kinda like altcoins in general. Tons of scams, only a few legit projects. And memecoins don’t really count as “legit” anyway, since they’re not expected to be stable long-term.
They’re built on short-term hype, like a mini ponzi - get in early, maybe you profit… stay too long, you lose.
