Unlike PMBs or plain mining hardware, there is a strategy of reinvestment here, and the idea is more or less to increase or at least preserve the % of hashrate of the network as the difficulty grows.
This is bullshit. You can as well invest into mining hardware and reinvest some part of proceedings into more hardware. Sure, it requires some work, but really not that much, I guess.
(1) Unlike PMBs or plain mining hardware, there is a strategy of reinvestment here
(2) and the idea is more or less to increase or at least preserve the % of hashrate of the network as the difficulty grows.
If you sustain your "this is bullshit", please claim that (1) or (2) is wrong (or both), and give a rationale.
The rest of your sentence, while true, is not relevant to what you quoted from me. When you see people buying milk at the supermarket, do you tell them they are stupid because they could just move to a farm and milk their own cows?
