Baikal Giant B, 7-Algo ASIC Miner, 168GH/s @ 410watts!! New, In-Hand USA Ship

works great!

I have several of these and they are very easy to setup . They run stable at 42 Celsius and produce 5% more than their rating. The down side is they are limited to only a couple of profitable coins . The listings that claim 7- Algo are false . The Giant B (BK-B) is a 5 Algo machine.

Plugged the Miner in and worked right away, makes about a dollar a day with easy nicehash setup. Didn't come with PSU so had to go purchase one. Definitely not new, already had historical mining.The 5 Algorithms it mines are as follows:Pascal, Lbry, Sia, Decred, and Blake256(r8 &r14)

Update 1-1-21: The profitability on these has swung slightly in the positive direction for one algo since I wrote the original review in Aug 20. The used price also went from below $100 to over $1000. When any of these ASIC miners are priced blow $100, it's a great time to buy them, but a horrible time to use them. They may or not pull a profit in the future, this is one example of one that swung in the opposite direction. You would have actually made out better buying the actual miner in Aug 20, then selling it now for the current demand price. But for every 1 ASIC miner that does this, there are dozens that never swing in the opposite direction. This is not financial advice, do your own research.Original Review below:I own two different types of Baikal miners and the BK-B aka Giant B is one of them. At my current electric rate of US $0.10 per kWh, all algos mine at a loss and there are very few coins available to mine. Some of the algos are dead because the coins were switched away from the algo because of ASIC mining. One coin was switched to a proprietary algo only available on one miner, and this isn't it.Right now, it loses anywhere from $0.40 or more mining.ASIC miners are what they are and market conditions have most ASIC miners mining at a loss now. When this miner first came out, it was almost $2000, but the price quickly fell with Baikal themselves having buy one get more than one sales. One of their other miners they were selling for buy one get 5.We are currently either at the end in the middle of a bull run in mining. There are a few rigs that mine at a profit, but this isn't one of them. Consequently, you can find this very miner for a very nice bargain price if you look around. You can then mine one of the handful of coins available at a loss and hodl bags of low valued coins if that's your game, hoping things might take-off during the next bull run, which many believe has already started.If this miner ever becomes profitable you can expect the bargain prices found at various sites to go away.Baikal isn't as popular as other brands such as Antminer, but ASIC mining in general is a niche hobby and that makes Baikal a niche of a niche. Technically this is an FPGA miner because it can be reprogrammed and Baikal has very sporadically updated their miners by adding new algos. However, the lid on deconstructing the firmware is tight and Baikal isn't popular enough where communities have sprung up with alternative firmware such has been happening with Antminer. Since it is an FPGA, it has great potential to be reprogrammed and updated, but so far only Baikal does it - and not very often.I have one because I got one for under $100 and it tickles me that I can buy a specialized computer that used to go for $4000 2-years ago for a bargain price. It's not the depreciation that does that - it's because market conditions right now have this miner netting pennies a day or losing when it used to net hundreds per day. Hey, it's a hobby of mine at I have some Antminers for the same reason.For residential people, these are loud and sound like a vacuum cleaner in the next room. There's great potential for developing alternative firmware and adding algos, but don't count on that. Active companies that support and update their FPGAs have their products going today for thousands of dollars and this could do the same but Baikal has chosen to let it collect dust and go for bargain prices. If you don't believe me, go to another popular auction site and search for this same model.Three stars because it is what it is - it's build like an ASIC miner and it does what it's supposed to and Baikal doesn't really update it all that often.
