Starting Ethereum dev here full of dApp projects. My concern is fees. Most of my applications are unfeasible at the current gas prices. How could I sell a digital product that costs 10 dollars with a 17 dollars fee? Just doesn't work.
But.. Ethereum is promising to reduce fees for a long time, hard forks, PoS, London, etc. Yet in every article about it, I don't see solid numbers on actual fee reduction. If fees are dropping from 17 to 12 dollars per smart contract transaction, it's still unfeasible. At 8 dollars, still unfeasible. For some projects to be viable we need fees in the cents range.
My question is: What can we expect in terms of gas fees reduction after London? What about after Eth 2.0?
