I would recommend you to investigate chains other than Ethereum. There are blockchains such as Polygon, Binance Smart chain, tron, near, avalanche etc that are ideal for microtransactions.

What is more, they have the same developed ecosystems like Ethereum with a lot of defi-projects, NFT-projects, DAOs so you will definitely find everything you need and you will pay less than 1$ as a transaction fee.

Anyway, you can check this link: https://ethereumprice.org/gas/ and you will see when ETH gas gets cheap.
