Bitmain ruled for a decade. The monopoly ends today.
Bitdeer's Sealminer A2 by is now shipping.
This company was born inside Bitmain, is backed by Tether, and trades on NASDAQ 🇺🇸.
Here’s the full story—and why it matters 👇
Bitmain has dominated bitcoin mining hardware since 2013 with Antminers.
Founded by Jihan Wu and Micree Zhan, they built an empire—always the number one, holding 80% of the market to this day.
No one comes close.
But then came internal politics.
Around 2019, the two founders started fighting for power.
Classic case of “two roosters in one room.”
By 2021, it ended with Jihan stepping down—taking some assets and business units with him.
That’s how Bitdeer was born.
A FORK OF BITMAIN.
At first, Bitdeer focused on self mining, hosting, and cloud mining.
Gigantic mining operations.
Then in 2023, they went public on NASDAQ as BTDR.
New capital for big plans.
In 2024, Bitdeer announced they’d start building miners—including their own ASIC chips.
So they acquired DesiweMiner (remember them?)
A Chinese bitcoin ASIC R&D team.
At the end of 2024, they promised their first flagship miner: the A2.
Supposed to ship in Q1 this year.
Slight delays, but…
TODAY IT BECAME REAL.
The Sealminer A2 is now shipping worldwide.
🔶 Hashrate: 220–240T
🔶 Power: 3630–3960W
🔶 Efficiency: 16.5 J/T
✅ Made in Vietnam—not China
✅ In stock—hundreds available now
Prices are great and tariffs are low—it qualifies as a “computer,” so it’s import-friendly.
Let us know if you want to try a few units, we now sell mini hardware too at Braiins.
But there’s more to the story…
TETHER INVESTED $150M.
And got ~25% of Bitdeer.
Remember that Tether made $13B profit in 2024.
So we will see their influence grow across the entire bitcoin space.
They’re the deepest pockets in the space—printing profits like no one else.
So yeah... mining power dynamics are shifting.
🟠 Bitdeer is here with cash and experience.
🟠 Tether is buying influence right and left.
🟠 BTDR is a real contender with a real product.
So WEN Braiins OS for 🦭?
We just ordered a few A2 units for testing.
We’ll take them apart, benchmark them, and see what’s under the hood.
Can we port Braiins OS to them?
Maybe.
We’ll report back soon.
Until then—watch this space.
Because...
Hardware is hard. But Bitdeer isn’t playing around.
And more competition is always a good thing ⚡
