I can not imagine how much money to be used to buy that miner.
Pretty simple
Assuming they are S19Pro, as I doubt they bought normal s19s with no discount it's around ~ 42 million but I assume they spend way less since they probably got a hefty discount. Nevertheless, as hight it might seem currently the whole farm will make for around 1.5% of the hashrate.
And there are so many conclusions that after halving crypto mining has become unprofitable, so then one can ask why someone buys such a large amount of mining equipment outside of China?
Well, it's investors money

so those are easier to spend. They raised 100m$ and then another 20m$, they have money to burn.
Last year we had a chance to read the news that
Bitmain plans to build a 300MW mining farm in Texas, which means things are changing after all, and of course with the blessing of the US government.
That project got
canceled in January.
