. But I can not understand why they are selling to Riot and not to small clients when they can get much more money from the retail clients.
Bulk sales have been always everyone's favorite, especially when both bulk and small pay the same, even better when the bulk buyers pay in advance, dealing with 1 client with 30k miners is a lot easier and cheaper than dealing with 15k clients for the same 30k miners, it's common sense.
Also does anyone has an idea what is the MOQ to be considered as a "large" client?
It used to be easier back then, nowadays with these massivly funded whales, i bet your order total needs to be a couple thousands of gears if you want to sit down with their sales manager.
