The people pushing mining here are doing it to maximise the secondhand value of their current GPUs. So there is a vested interested in them posting in the GPU section because it makes their new GPUs cheaper.
There is afterall a whole subsection devoted to mining here,but as the OP also said this:
just to irritate those kind of people.
It's (again) making their hobby more expensive and harder to pursue. Can't blame them really.
Because the people posting in this thread are the contributing reason to this. They will pay any cost for their GPUs "because mining",hence making sure next generation RRPs will also go up. Instead of criticising retailers,AMD,Nvidia,etc on their jacking up of GPU prices,they find more and more reasons to "have" to pay scalpers prices.
It's a form of Stockholm syndrome where retailers,AMD,Nvidia,etc can do no wrong and all the wrong is directed towards normal consumers who want a GPU to play a few games on,etc. This is the reality of the modern enthusiast - more worried about mining,stocks and shares,etc than the actual hobby of gaming,etc. Even a number here admitted they don't game much if at all.
They are the one causing scalping of new GPUs at high prices,and causing the secondhand market to go massively up in price,because they are "not in the wrong" for paying above the odds for GPUs.
Hence,they will defend what they do until the end,and attack gamers who just want a GPU to game on at normal prices.
The worst thing many of the ones pushing it here,invested early so actually have lower startup costs than someone doing it. It realistically is a Ponzi scheme as many have said here.
I am still waiting for someone asking advice on what £20000 Focus they want to get,to be told to spend £50000 on a classic car,since it can generate "extra income".
