That's true of the supply will not determined but as a subtitution and there will be a burn mechanism that will be using by ethereum.
Thats like a 100 page document that will take me all day to read.
If the supply cap has already been mentioned like you stated then please kindly remind us what that cap is?
Then you go on to say that supply will not be determined but instead there will be a burn mechanism.
So basically ethereum is like a fire that will forever burn in a forest with infinite of trees/wood to throw at the fire?
I will try to make it more simple
Here's an important point about the supply
A: I don't know about fixed ETH supply, but we may get to a point of decreasing ETH supply. Indeed, we are looking into transaction fee schemes that burn ETH, and burnt ETH may outweigh minted ETH. [Justin Drake]
You can also try to see the interview about the supply cap of ethereum with vitalik here
https://coinmarketcap.com/headlines/news/ethereum-supply-vitalik-buterin/
Even vitaliks says that if that's still a rough estimation and it's not yet fixed
JD as a part of ethereum foundation didn't even know about how exactly the rough number of supply cap for ethereum which mean only god vitalik that knows it.
some parties were also predicting the max supply of ethereum will be around 112,000,0000. but we have already passed this today
