Proof of Work (PoW) is the nature of the Bitcoin ecosystem. Fiat money generates a feeling of selfishness in people because the fiat system is selfish in its conception.

Bitcoin, on the other hand, motivates people to share what they can of what they have and the most interesting thing is that the more you share, the more it comes back to you, even if this was not your goal. It's great how when you receive SATs for your work you feel very motivated and in many cases they are not large amounts, but it motivates you because you feel that you have helped someone and that someone has shown you that they appreciate it and that is their way of doing it.

But really this Stacker News project is impressive in that sense and I never tire of saying it. A great idea, thanks to its creators. Thanks to you too for the work you do.
