Join us for a short review of the Antminer S9 Special Edition from Bitmain. You know it now, Bitmain is the most known and active ASIC miner producer, releasing tens of ASIC miners every year. This very ASIC miner allows you to mine coins using the SHA-256 algorithm like Bitcoin or Bitcoin Cash. It is one of a large range of SHA-256 ASIC miners from Bitmain (S9, S17, T17…) and settles for low-middle range budgets.
In September, for the first-time bitcoin’s two weeks average hash rate has reached 85 exahashes/s (85 million Th/s) with a new difficulty record of almost 12 trillion. This marks a new point in the cryptocurrency mining market as more than 300 000 mining machines may have entered the network in the last 3 months along with an incredible growth of mining equipment demand which is exceeding the supply.
The BITMAIN Antminer S9 SE reaches a hash rate of 16Th/s and an efficiency of 0.08j/Gh with a power consumption of 1280W. It was released in July 2019 and is one of the most profitable SHA-256 ASIC miner.
At a price of 750$ with Sesterce Mining, it gives you a daily income of 3.97$ (09/23/2019). With the electricity cost of 0.03$/KWh with Sesterce Mining hosting service it leaves a daily profit of 3.05$.
Here is a quick comparison with SHA-256 miner for different budget:
Data for the 09/23/2019 with the electricity cost of 0.03$/KWh (Sesterce Mining hosting service)
The BITMAIN Antiminer S9 SE, is a safe choice (because it’s a SHA-256 miner) that will surely give you some results over time especially with the electricity cost of 0.03$/KWh of the Sesterce Mining hosting service. Moreover, the increase of SHA-256 ASIC miner efficiency over the years is relatively low compared to other algorithms.
However, it is not the best one if you look for fast and short-term income as it can be less profitable than some other miners in the first months but is characterized for its relevance over months or even years.
For its range of price, the BITMAIN Antminer S9 SE is definitively a good choice.

A blockchain is a database accessible to people all over the world and operating without a trusted third party. It uses advanced cryptographic techniques to reward those who process and secure this data (in the case of Proof-of-Work). Since the Ethereum blockchain, this database has become programmable with the implementation of Smart-Contracts, decentralized applications (Dapps), and decentralized organizations (DAOs).
Today the art market represents more than 14.58 billion euros in transactions. Most works of art have an extrinsic value, which is mainly based on the certificate of authenticity provided by third parties: the artist himself, but also gallery owners, art dealers, auctioneers, museum curators, and private experts. However, according to Bloomberg, nearly 10% of the value of transactions on the art market comes from forgeries.
As we’ve seen last week, a growing narrative within the ecosystem is pushing the idea that Proof-Of-Work is a bad system that will inevitably fail in time. The most common proposed alternative is Proof-Of-Stake or PoS [...]
