But really what we need is low-cost, low-energy miners, to widely disperse the 'consensus'; The current high-power usage of ASIC in China is what is causing fee's to skyrocket.
There must be diversification of 'mining', can't have it all in CHINA. Trouble is CHINA also makes all the Mining HW,
Even the better alt-coins have given up fighting the GPU wars, and have just let bitmain sell equi-miners, and eth-miners; There used to be a real drive to keep the MINING on the CPU, so that everybody could mine & host a node, but now while you point out there are 100k dispersed nodes worldwide, all mining is done is CHina, or the majority, and all user the Chinese HW, which all calls home to china;
Real problem for future of BTC, but given that CHINA owns alll the media conduits, and exchanges, and pools; Nobody can seriously do anything except remain silent.
Things are not that simple.
THere are reasons for mining centralization in China.
In China they have very cheap energy, as they locate some mining farm near the
largest hydroelectric power stations in the world. It is also cheap to buy mining hardware in china. They have the ideal economic situation to mine bitcoin...
