Yep, buddy of mine just lit up a 240 GPU mini farm last week hashing 7GH on ETH. Planning to add another 400 cards over the next few weeks, slowly turning into a mini whale.
Omg. It's the cancer of this planet - looking for more profit, when difficulty is going skyhigh... Why everybody can't be good with 10-20-50 gpus even 100. No everybody whose in take not 10 but 200 cards burning lots of power (especially in Ukraine or Russia or Belarus where power cost is 2-4c), they mine like hell, but it's going to be less for everyone when they try to catch up with the biggest cake... 1000 gpus farms are now small... My god what it has ddone. About 19M Cards is mining eth alone? WTF?
What do you expect? Its pretty much free money. Who would say "no" to that.
It's greed.
The people with a fuck load of capital want to crave themselves out a large slice of the pie, so they can earn more than the next farm. But it is a vicious cycle, the more gpu's added the more you need to add to stay competitive and then electricity slowly eats away at the profit. That is when a coin goes sideways instead of pumping.
It screws the small miners and gamers AND it screws AMD long term in the gaming market. Gamers want a card can't buy AMD and see it is priced high so they go with Nvidia which shrinks their gaming market that they earn the most from.
Well that's just how the mining game works.
