He deserves at least 90 days of fees.
After that he could lower them.
And after 180 days end them on Zec coin.
There is a limit to full speed perfect software for Zec coin.
And claymore is getting close to it.
As for fee retirement it is fair but I am sure he would think differently.
My basis is. He did say 100 or 200 hours of work . His risk was the coin could crash and die.
So let's say 200 hours of coding is worth 20000 to 40000.
Don't you think in 90 days he will earn far more then that?
As a miner I may have roi in say 150 days if lucky.
And my risk was 28 gpus and mobos etc. so say 7k .
My mining is not the same for the game as his coding. But my roi is far longer then his will be.
He's already earned $40k, how do you math? His fee structure earns him $1000s every day.
He is worth that.
