I am very confused about the process of buying S9's from Bitmain. I have have read on this forum that to buy from Bitmain you have to follow their Twitter account and wait for them to tweet about a batch being released and then buy from there.
But then eBay is filled with sellers saying they have pre-orders that they have purchased from Bitmain for future batches that will ship at a certain date. How is this possible?
Can anyone explain?
These sellers already pre-ordered last week or the weeks before.
Now they are selling without stock in-hand.
