Could you explain how that works, or link to a good tldr article? I've read something about that it works based on amount of coins that you have rather than how much gpus/cpus/asics/..s you have, but I still don't really get it. Also what keeps Bill Gates (or his equivalents) from mining 90% of the coins? Or is mining different there? What about double spending attacks?
Lots of questions... any good place explaining this? Thanks :)
