IF war with China should happen this summer with the UNited States,,, could China hack Bitcoin if it had to regardless of cost?
War doesn't have any connection with bitcoin. Both are different thing. But Chinese domaince 51% of mining pools, so they can drop bitcoin price but that wouldn't going to benefit for them, rather that would be harmful for their economy
Yes, that is true. But if the war gives impact to everything we have, then that could have a connection with bitcoin. Imagine if that war destroys everything, including internet connection or communication in all countries, I am sure that will give impact too with bitcoin. Bitcoin or cryptocurrency will not work well because we cannot connect to the network or use bitcoin and the other coin.
I don't think that they will drop bitcoin price if that war happens, but that could be possible if they know where is the mining pools locate so they can destroy or eliminate the company. That is only a scenario which we don't know if that will happen or not, but we need to prepare for anything that might occur later.
