Just like direct CPU mining isn’t possible anymore, it could be reverted and turned the other way around. What do they do next, start buying exaggerated amounts of CPUs?
Do you really want to find out how many flops Oak Ridge has in their basement?
Attacking a CPU-minable coin would be a thousand times easier for someone with deep enough pockets, there is enough computational power standing instantly in datacenters no home miners will be able to offset!
Sarcastic as it sounds, bitcoin miners will not give up their mining rings to a centralized entity such as the bank which already have its own existing centralized financial institutions that don't really bank on the decentralized nature of bitcoin.
So, let's assume you have 10 s19, the current brand-new value is $900 a piece, each mine $6.3 a day before electricity so that would be at around $1800 a month for all of them, and the banks come in and offer you 50k for all of them. Tell me without lying you won't be selling!
The banks have to pay so much to buy the miners, and even if they purchase the all mining rigs of the world then what? It will be a disaster for them to run all those miners.
You know the mining Asics require energy and the banks aren't the providers of energy so in order to run the miners the banks will have to either purchase renewable energy sources or they might rely on the available energy resources of the countries where they run their operations. In both cases they'll have to pay a lot more to run the miners.
So banks are the middlemen to billions of deals, that negotiate mergers of companies worth billions, that have all the information at their disposal, that have already business relationships with every single major power supplier will somehow have trouble finding 10-20 GW of power, but companies who are not even in top 1000 in the US by revenue have no problem buying a **** nuclear powerplant!
I love this kind of flip-flop, one time we have banks controlling every single aspect of the economy, having absolutely everything in their clutches and then we have them unable to operate a damn datacenter that is 1/10 of what google has. Isn't this a bit ridiculous? A bit too much?
