OP, if someone "discovered" an unlimited resource of free energy, the sun?, and harness it, he would be murdered by the cartel of largest oil producers in the world, a cartel of electricity providers in the world, and other groups/cartels that don't want change in the current "order" of the system.
BUT, let's pretend, "someone" was allowed to "wield" that power, do you actually believe an attack on Bitcoin would be first in his/her list of "to-dos"? What about space-travel? Deep sea exploration? Or WAR?

The Solution
PoW is a failure. PoS is a better system. With Ethereum 2.0, Ethereum is slowing moving to PoS. The threat of someone having massive amount of electrical power is eliminated in a PoS system. As soon as the news breaks out, Bitcoin price will plummet. PoS and Ethereum 2.0 is the future.
All that, because you want to shill your shitcoin.
