Where to buy niche meme coins

I follow a few meme coins on Twitter and they're doing pretty well. I'm looking for Web3 exchanges for smaller tokens on the Solana blockchain.

In particular I found

1. RawrXD
2. Glorp
3. (a coin with an offensive name)
4. Sigma
5. Gigachad

I think these coins are all based on the Solana blockchain

They have Telegram accounts but they require some sketchy identity verification to get into. Not otherwise able to message the accounts directly because I don't have a checkmark on X.

Where do you guys find niche meme coins? I'm fully prepared to lose all the money I put in them but I don't mind gambling a little to see what happens. Thanks
