As we all know, mining is now completely centralized.
you thinking some way doesn't mean everyone else thinks the same and it certainly doesn't mean it is correct!
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.
it is not
that expensive to need "big money". and nobody is preventing YOU from buying an ASIC and mining bitcoin with it. the only problem is that others who buy ASICs believe in bitcoin whereas YOU don't and because of that you don't want to make that kind of investment!
