Blackminer F2 is another miner produced by HashAltcoin. The multi-algorithm miner comes in hand for those looking to mine exotic coins. There are nine algorithms under this miner, which is a plus for users. The F2 model is an improvement from the F1 and clearly has some advantages. Kadena is one of the top coins to mine, and you can mine nearly 9 exotic coins. Learn more in this detailed Blackminer F2 Review. 

Blackminer F2 Features and Specs

Once you take a look at the miner's dimensions, you feel that it’s perfect for large-scale mining. It takes less space and weighs less than most miners. There are no naked wires at the top, and the setup process is easy and quick. 

Unfortunately, there’s no ASIC support for this miner, which means you can’t track the progress while away. The miner comes with a maximum voltage of 12V and power consumption of 1202W. DigiByte Odocrypt has the largest power consumption.

The F2 continues to be a stable miner that performs exemplary in terms of mineable coins. There are no mining pools to join with this unit. We couldn’t get any mining pool that supports this unit. To get a hold of the miner, you should contact Blackminer or the FPGA shop. 

A few other stores have this miner, such as unlimited miner. HashAltcoin is the main distributor of this mining equipment. 

Since it uses Custom ASIC chips, the performance of this miner is better than the predecessor. Further investigation shows you can use decentralized mining pools to get ahead. These decentralized mining pools include AntPool, P2Pool, and SlushPool.

Algorythm of F2 Blackminer

As indicated earlier, the miner comes with nine algorithms. There are three compatible hashing algorithms on this miner. The compatible algorithms include CKB, Odocrypt, Veriblock, and Versus2.

You get an FPGA chip type with no information on the number of chipboards and chip size. All the algorithms found on this miner have one issue, they are vulnerable. Unlike the Bitcoin algorithm, the nine algorithms can face multiple attacks.

Efficiency of the F2

We don’t get an exact number when it comes to the efficiency of the F2 Blackminer. That said, we have to go with the standard efficiency of 67.6G/682W. Miners should also note that each algorithm comes with different power consumption. 

The power enables the miner to perform differently depending on the algorithm. Power consumption ranges from 682W to 1202W. That double power gives the miner the much-needed boost to perform at optimum levels.

Hash Rate of Blackminer F2

With each algorithm, there’s a different hash rate that comes with it. The hash rate also varies between 6.6 GH/s and 67.6 GH/s. A higher hash rate means a more secure hashing network. You get to mine coins faster than when using a lower hash rate. 

Miners also get a secure mining experience while using a higher hash rate. All these algorithms will thrive to outdo each other and mine coins faster. 

Operating Temperature

For the miner to work effectively, it must be under recommended manufacturer settings. Miners should use the miner at a maximum of 30 degrees Celsius. The operating ambiance for minimum temperature is – 20 degrees Celsius. 

There’s no information from the supplier in regards to the availability of fans. Having a fan will help cool the miner and avoid overheating.

The Profitability of Blackminer F2

As soon as the Blackminer F2 hit the market, the miner did produce reasonable profit margins. Today’s market may not favor mining some of these coins. This should not deter users from buying the unit. Once the market favors mining Kadena and other related coins, the unit becomes highly profitable.

Warranty of F2 Miner

The distributor offers a 200-day warranty for the miner.

Kindly note that the above information is for educational purposes. We won't be held liable for any losses incurred while buying or mining with the unit. Crypto mining is a risky investment.
