A brand new S9 from bitmain is around $1300, if you are paying $4000 you better ask for some lube while you get bent over. Also from a third party you get zero warranty. Dont do it.
where do go get s9 for $1300 these days ??
LOL YOU DON'T SADLY.... they are way more now....
What does a s9 consist of i went on bit mains website and it doesnt really give you all the specs.... very curious as what they are built off of as I have built high end computers and I'm betting there are ways to get the hash rate sped up to mine faster
