The demand for Bitcoin mining hardware seems to causing some strange decisions among the ASIC manufacturers and one such is apparently the announcement of the Bitmain Antminer V9. A small 4 THS SHA256 ASIC miner that uses 1 KW of power, so not very efficient, but it comes cheap at just $345 USD. There are already some speculations that this could as well be old hardware renamed and refurbished as a new product to clear up some old mining hardware used by Bitmain in their mining farms in China instead of having to relocate it to a new place. This batch has a MOQ (minimum order quantity) of 5 units and all ordered quantities can only be multiples of 5 (10, 15, 20 units and so on) with the maximum number of units in a single order up to 300. The shipping for all confirmed orders will start after March 1st and payment accepted is only in Bitcoin Cash (BCH) and USD wire transfer.

All in all not a very exciting new announcement of a new ASIC miner from Bitmain, efficiency wise the “new” hardware is disappointing for the performance it offers at the rated power usage. So it seems to be targeted at users looking for cheap hardware that have really cheap or even “free” power, otherwise it just does not seem economically reasonable to buy these miners at the moment.

If you are a small crypto miner and not a large mining operation you may find it very hard to acquire up to date Bitcoin ASIC miners as the demand is still pretty high and the wait time is long. If you manage to find an ASIC miner is stock the chances are the price will be significantly higher as they are being resold with serious profit by people that prefer to make money this way instead of mining with the devices. At the moment there are pretty much 4 main manufacturers of Bitcoin ASIC miners that sell to end users and in small quantities and as you might expect they do not have anything in stock as the wait time is in months.

1. Bitmain AntMiner S9 (13.5 THS)
Bitmain is the most popular name among the ASIC manufacturers and probably the biggest one as well and even they are struggling to have stock of the AntMiner S9 ASIC miners they produce. It is interesting to note that the S9 has started shipping in the summer of 2016 and is still their top product. Bitmain has already sold all of their production up until the end of March, so when they release a new batch it will be scheduled for delivery sometime in April earliest.

2. Canaan AvalonMiner 821 (11 THS)
Canaan has been making their Avalon miners for years, though they were a bit slower in terms of specifications as compared to Bitmain and not as popular among end user miners. Their latest AvalonMiner 821 was announced in December last year and just started shipping its first batches for people that have preordered early. You can currently preorder AvalonMiner 821 for shipping/delivery in the second half of March, so you can probably get these a bit earlier than if you wait to preorder an AntMiner.

3. Ebang Ebit Miner E10 (18 THS)
Ebang’s Ebit miners are mostly popular in Asian countries, though they are trying to get to a wider market and their latest announcement of a 10 nm ASIC miner – the E10 made some waves. It is however an expensive device and still hard to get with a minimum purchase quantity of 20 units and all batches already sold through the end of March.

4. Halong Mining DragonMint 16T Miner (16 THS)
Halong Mining is a newcomer that just recently announced their plans to enter the Bitcoin ASIC miner market to try and fight with the market dominance that BitMain already has. They are still yet to start shipping their first devices in March this year and you cannot currently preorder units on their website with new batches probably to be available for April earliest.

This came as a bit of unexpected surprise, but it seems that BitMain already has a working ASIC miner for the Blake (2b) mining algorithm (and maybe even for other variants of Blake) and they have announced their plans to start shipping the Antminer A3. The Blake 2b crypto algorithm is currently being used by SiaCoin (SC) and last year there was a pre-order for an official SiaCoin ASIC miner the Obelisk SC1. BitMain’s ASIC miner however seems to be arriving much earlier with similar specifications and price, so anyone that has pre-ordered an Obelisk SC1 might not be that happy. On the other hand people that are interested in getting into mining SiaCoin and missed their chance with the pre-order might order now from BitMain and get the device shipped in 10 days after payment according to the company.

BitMain Antminer A3 Specifications:
– Product model: A3
– Hash ASIC type: BM1720
