So if a country with large resources wants to fuck up bitcoin they need only have 2 large hydoplants and 52% of the hash.

Thus CHINA could do it for about 6 billion

let check the math.

we are at 330 eh or  330,000ph or 330,000,000th

3,300,000 s19 pros = the network.

say 1000 for 1 or

3,300,000,000 cash to match the networks hash

let China take over bitmain build the units and they would make some extra ones so 4 billion means

4.0 all china 3.3 rest of us

you need power 4 units = 13.2kwatts
