They just sold out yesterday. Lketc was a preorder a few weeks ago, dont forget.
Also, the price difference from 3000 to $2200 is huge.
if you think one miner that you are supposed to receive two weeks later at the price of 2200$(actually 2400$ because you need pay the shipment fee) is better than one miner ship out tomorrow at the price of 2800$(shipment fee included), you can wait.
Whomever bought the last of Bit tech's units paid ~4.4BTC each. Lketc wants 6.21 at the moment which is $2,922.71.
