Short post to say that Bitmaintech has begun pre-sales (shipping september…or later) of a new X11 miner, the D3. It hashes at 15000mhs for 1200w, and it is a big improvement over current miners which are also more expensive. A lot of people are jumping on this as it becomes available, but please remember the rules of crypto. No pre-orders. Although Bitmain has a proven track record, this is still a pre-order and many things can go wrong. Keep in mind if you do get refunded for the order, they will pull the same trick on customers as PandaMiner recently did, which is pay back the USD value at the time of purchase. If bitcoin goes up you are out of luck. And of course, mid September at earliest. Which means difficulty will probably be much, much higher by then. But it may still be worth it, up to you to decide.
Edit: Seems Innosilicon is also pre-selling the A5 “DashMaster”. Cheaper and more hash. So there you have it, your gear’s ROI is uncertain.
