It's indeed not great for investors to have this option open to token creators. A creator can mint token and you wouldn't even know about it if you don't go scanning throught the blockchain. Evern like that it's difficutl to figure it out. When you create a token on Solana, 100% are minted immediately and if you want to you can create contracts that distribute the tokens until there are none left. It's much more transparent and easier to predict the market evolution of a token.
