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.
Questions:
My take on this issue is that those who took mining serious in early days (when Bitcoin can be mined using CPUs) get reward because of putting there trust on something that was struggling to get acceptance. Those who joined mining when Bitcoin got fame and acceptance have to invest huge money to get the benefit.
