So show us the proof this was done with ASICs.
Prove it was done with GPU's
The educated guess would point to ASIC's being used, as it is commonly discussed that this exact attack is the primary risk of ASIC's towards small cap coins...
However when one entity currently controls over 50% of the zec network, it is also a risk to zec... and it was zooko that took the educated guess that bitmain has over 50% of network hashrate now.
I agree sense china steals from the US any time they can who to say the CEO doesn't do some shandy shit with butmian there not heard account able for anything they do, so why not i bet is how they see it and trumps giving china a pass with ZTE makes "China Great again" is new the buzzword.. so trump can pad his Picket with 5 billion and who knows how much more ..
cryptomined you were right two year ago about the trump reality show and china is taking advantage of it any they can including with who controls the cryptosystem.
I'm willing to bet the CEO of butmain has to ask china's President to do some stuff to the US and the world or China has a lot of say in what butmain does .
This is a major risk with allowing a chinese company to control the hashrate of any POW coin... bitmain and other chinese ASIC manufactuers can easily be controlled by the chinese government... and that is not a nice thought. (since i live in china i can speak from being on the ground here)
