Keeping eye on difficulty and profitability once these hit...
Why would you expect that with no information on the quantity of miners sold / shipped, that makes no sense. For those that bought I hope you're right...
In searching the threads it appears some of the Halong B29's (Decred) and B52's (SIA) have arrived to those who ordered ... I think some are still waiting... not sure the Innosilicon miners have shipped (this thread says shipping starts today) ...
With these SIA miners (miners B52 and D9) over 4 times the hash power of current Bitmain A3 products , and plenty of those out there in the market, I still give it a few weeks to see shipments and home miners get plugged in before I make any determinations about the difficulty changing for SIA... as for the D9 there's no Bitmain miner so that's nice , but there still should be a huge spike in difficulty in the coming days...
I haven't seen any confirmation of units being shipped from Inno. There's several of us who pre-ordered who have not received any tracking number.
The Halong ones you mentioned were a super small batch that was sent out a few weeks ago - and then went "unavailable" until Inno announced the D9 and Sia miners.
Keep in mind - They said 2-3 day payment confirmation and shipping on April 27th. It's now April 28th in China and no one's received a tracking number. The miners are sold out, but if you pre-ordered and paid; shouldn't you have your tracking number in hand now?
