"Proof-of-work is essentially one-CPU-one-vote."
Satoshi nakamoto
As we all know, mining is now completely centralized. Big money buys expensive equipment in the form of ASIC / GPU / FPGA devices and deprives everyone else of the right to participate in the issue of cryptocurrencies.
I kinda feel the same, this world is turning to a centralized world and only people with big money will rule everything. But it isn't end yet, Satoshi has given the idea of decentralization and invented Bitcoin as a little proof of his idea.
Now, it is our job to think how to improve and make the his idea as a complete real product.
