You do realize it's not 2012 anymore, right? CPU mining is long dead.
This is news to me. I have found blocks using a CPU in 2016.
Sure, but CPU mining is irrelevant next to GPU and ASIC mining.
1) It's a FACT that few people can get access to ultra-powerful hash miners
Most of people CANNOT invest tons of money in superminer for speculation, I have a high end home PC pretty expensive and if I compare ,u hashrate to top miners of most popular pools its power i light years distant not even in the same universe.
2) The concept of miners contribute to the currency has sense when the hash power is proportional to the blockchains needs, if there is overmining speculation becames a way to grab as much coins as possible. This concept is very easy to understand. There is monstrous power used in most popular coins mining for few transactions. So say that is only a meritocratic reward is bullshit, It's a gredy game for who has most power.
3) Is for you is fair that few richest people that can affort mining cloud controls most of the money, you have to consider fair also that original developers control most of the coins. To me fairness means a proportional distribution among people... According to you isn't clear what means and what is the "merit concept".
Fair means everybody can mine it not that everybody gets the same amount. What you're talking about is socialism.
You basically have an issue with everyone who invests more than you do while you could invest as much money as you have and become a superminer yourself.
