After six years, the block reward will decrease by a factor of 10, and after eight years, by a factor of 20. How do you hope to retain miners in your project with such a decrease in rewards?
Maybe @gaelium is confident that the price of 5GAEL will be enough in about 12.5 years?
Both fair questions, taking them together.
Small correction on the emission first. It does not stop at 1B. The reward settles at 5 GAEL per block and keeps going from there, permanently, so there is no max supply. That tail is deliberate. Ravencoin, which we forked, caps at 21B and once the last one is mined the only thing left for miners is transaction fees on whatever volume the chain has that day. Bitcoin has the same problem waiting for it, just further out. We would rather keep paying for security than find out how that goes.
On retaining miners, the reward size is not really what keeps a rig running. Difficulty is. If the reward drops and nothing else moves, some miners leave, difficulty falls, and the ones who stay find more blocks each. That balance is not something we control, it is the same mechanism every PoW chain lives on.
What we did choose is where the coins go. The emission is front loaded on purpose, the early years pay the most, and it is 1B spread over twelve years rather than everything minted at genesis for whoever got into a presale. There was no presale, no ICO and no investor allocation here.
As for whether 5 GAEL will be worth anything in twelve years, I am not going to pretend I know. Nobody does, and anyone telling you otherwise is selling something.
What I can tell you is what happens in the meantime. Wallets on Windows, macOS, Linux and mobile, our own pool, six other pools running the coin including Mining Dutch who added us yesterday, and the daemon patched within 48 hours when the Ravencoin consensus bug went public in August while several forks were still exposed. The code is a Ravencoin fork, which is a Bitcoin fork, and we adapt it where we need to rather than leaving it as it came.
That part we do control, so that is where the hours go.
