On June 17, 2019, Chinese mining hardware giant Bitmain Technologies announced the Antminer S9 Special Edition (SE), a low-cost miner priced at just $350 per unit. The new rig delivers a hashrate of 16TH/s for SHA-256 algorithms (supporting Bitcoin and Bitcoin Cash), with a power consumption of 1280W and an efficiency of 80J/TH. The first batch will ship from July 21 to 31 on a first-paid-first-ship basis, with a strict limit of 10 units per order to prevent hoarding.
Specifications and Market Positioning
The S9 SE weighs approximately 4.5kg and emits around 76 decibels of noise during operation. It features three hash boards with roughly 180 custom Bitmain chips, though the exact semiconductor process remains undisclosed. In contrast to Bitmain's high-end offerings like the S17 Pro (53TH/s) and S17 (56TH/s), the S9 SE is clearly targeting solo miners and small-scale operations seeking affordable entry points.
Historical Context and Profitability
At the time of the S9 SE's release, Bitcoin was trading above $9,000 and BCH above $400, significantly boosting mining revenues. According to Bitmain's announcement and industry reports, even older S9 models (11.5TH/s, 2016 vintage) remained profitable at $0.13/kWh, earning about $0.75 per day. Coinshares' June 2019 mining report noted that used S9 units were selling for as low as $150 (about 700-800 yuan) on secondary markets, and even older Antminer S7 units were being reactivated by some miners.
The low-cost S9 SE arrives when mining difficulty and competition are rising. Bitcoin network hashrate was around 54 EH/s and BCH at 2.5 EH/s, totaling 56.5 EH/s. However, miners in regions with extremely low electricity costs—such as Sichuan, China ($0.01-$0.04/kWh) or Iran ($0.006/kWh)—can still profit from even less efficient hardware. This makes the S9 SE an attractive option for those with access to cheap power.
Trade War Impact and Competitive Dynamics
U.S. buyers face additional costs due to ongoing trade tariffs: a 2.6% tax and a 25% import duty on mining equipment imported from China. This could push the effective price above $450 for American customers. Meanwhile, Bitmain's move to offer a budget miner comes as the secondary market for old rigs remains active. The S9 SE effectively bridges the gap between obsolete 11TH/s S9s and modern high-efficiency miners, providing a new option for price-sensitive buyers.
In summary, the Antminer S9 SE represents Bitmain's strategy to capture the mid-to-low end of the mining equipment market. With crypto prices rallying in mid-2019, the miner is poised to become a popular choice for hobbyists and small operations looking to enter or expand their mining activities without breaking the bank.
