Max supply is 90m. Read the white paper. Stop spreading FUD.
From "the whitepaper" which I guess (?) you mean as this:
https://github.com/ethereum/wiki/wiki/White-Paper#blockchain-and-miningwe find:
"0.26x the total amount sold will be allocated to miners per year forever after that point."
That's quite clearly an unlimited supply. Nothing about 90m in there
However thanks for getting me to check it out. This is hardly a paper. It is a vague meandering generalization of interesting ideas, at times contradictory and never precise. The author doesn't make any attempt to use academic references. Not like it matters much anyway, the details we need should be in the code right? After all, consensus is shaped by the code not by the
whitepaper git hosted blog, and we've all seen words that don't quite match reality haven't we. Maybe the supply is limited after all?
So lets go take a look shall we? Source is online right? Oh look, it's not one repository, it is 100 repositories to wade through. Looks like mostly documentation, fragmentation, eneterprisey stuff. Some searching leads me to believe most people use "go-ethereum". Inside "core" there I find in "fees.go" :
var BlockReward *big.Int = big.NewInt(5e+18)
which gets used by the AccumulateRewards function in state_processor.go. For what little it is worth here, in my opinion this looks like a fixed reward.
