This is very interesting in the light of "Satoshi owns 1 million coins" myth that is being brought up so often . It seems like Satoshi was against concentration of big amounts of coins in one hands, so this might mean 2 things:
1. Satoshi didn't mine any disproportionate amounts of coins, there were many early miners that we don't know about.
2. Satoshi did mine big amounts of early coins, but he destroyed them or don't plan to spend them in any way.
In his book, Digital Gold: Bitcoin and the Inside Story of the Misfits and Millionaires Trying to Reinvent Money, Nathaniel Popper had published an email conversation between Satoshi and Laszlo.
Laszlo’s CPU had been winning, at most, one block of 50 Bitcoins each day, of the approximately 140 blocks that were released daily. Once Laszlo got his GPU card hooked in he began winning one or two blocks an hour, and occasionally more. On May 17 he won twenty-eight blocks; these wins gave him fourteen hundred new coins that day.
Satoshi knew someone would eventually spot this opportunity as Bitcoin became more successful and was not surprised when Laszlo e-mailed him about his project. But in responding to Laszlo, Satoshi was clearly torn. If one person was taking all the coins, there would be less of an incentive for new people to join in.
A big attraction to new users is that anyone with a computer can generate some free coins. When there are 5000 users, that incentive may fade, but for now it's still true.
GPUs would prematurely limit the incentive to only those with high end GPU hardware. It's inevitable that GPU compute clusters will eventually hog all the generated coins, but I don't want to hasten that day. If the difficulty gets really high, that increases the value of each coin in a way since the supply becomes more limited. The supply is the same: 50 coins every 10 minutes.
But GPUs are much less evenly distributed, so the generated coins only go towards rewarding 20% of the people for joining the network instead of 100%.
I don't mean to sound like a socialist, I don't care if wealth is concentrated, but for now, we get more growth by giving that money to 100% of the people than giving it to 20%. Also, the longer we can delay the GPU arms race, the more mature the OpenCL libraries get, and the more people will have OpenCL compatible video cards. If we see from the difficulty factor that someone is using too much GPU, we can certainly pick this OpenCL stuff up again then. Maybe my effort to maintain GPU innocence is running out of time. It's worked out so far.
If you interpret the mail as it's, I don't think Satoshi was against concentration of wealth and Bitcoin isn't designed to address the issue of wealth inequality.
According to Nathaniel Popper, Laszlo did slow down.
he did slow down -- but others also soon began doing their own gpu mining after bitcoin gained in popularity after the first slashdot item on bitocin.
