I've seen people making millions of dollars selling NFTs on popular blockchain platforms. Things that were thought to be worthless are now worth a ton of cash. While all of this sounds great, it's not easy to create a unique NFT that would gain demand on the market. High gas fees on the ETH blockchain, makes it unprofitable to sell NFTs on it. Binance Smart Chain would be a better choice, but mainstream adoption on the platform is still low these days (when compared against Ethereum).

I'm wondering how do I make money with NFTs? Some guidance would be greatly appreciated. Thanks in advance.
