Bitcoin mining has come a long way since the early days. Bitcoin mining can be a challenge, but with the right equipment, the rewards are well worth it. Today’s Bitcoins are valued at about $6,000, so there’s a pretty big incentive to mine for Bitcoin blocks.

You can purchase the latest Bitmain Antminer S9I Bitcoin Miner Here. That’s the latest at the time of this writing. This one comes with a power supply, but they have other options if you don’t need the power supply. They also Have the Bitmain Antminer S9J Bitcoin Miner, for a bit cheaper, but it’s not as efficient.

Is the Bitmain Antminer S9 Bitcoin Miner the right tool to keep in your mining arsenal? In this guide, we’ll break down all the specs. Keep reading to learn if an Bitmain S9 Antminer Bitcoin Miner is in your future.

The Bitmain Antminer S9 Bitcoin Miner: Gamechanger or Not?

Since Bitcoin Difficulty was created, it’s recorded a number of strong increases, sometimes across consecutive months. All the investment in Bitcoin mining operations and technology sparked this massive growth. The interest in Bitcoin doesn’t show signs of slowing down anytime soon.

This growth is incredible and has made Bitcoin the most powerful computing network in the world by a long shot. This growth also had a surprising side effect: greater centralization of mining farm operations.

The profits have grown most in areas where mining’s the most profitable, such as China. This has forced some competitors out of the industry altogether since they can’t keep up if they’re in the wrong area or do not constantly upgrade their Bitcoin miner’s. These competitive advantages have also removed large numbers of hobbyist miners from the Bitcoin market. For anyone who’s not invested, it’s almost not worth it anymore; unless you get free electricity or you buy the latest Bitcoin miner the day they come out.

The few people still mining from their homes are generally working to help decentralization or support the market. Unless your operation is super-efficient, it won’t be very profitable.

As these profits dwindle for small-time miners, people are looking for ways to turn things around. Can the Bitmain Antminer S9 Bitcoin Miner put hobbyist miners back in the game, or is profitability a lost cause for them?

Let’s take a look at the factors that will help us answer this question.


One important side note: before investing in the S9, you’ll need to be sure you have a Bitcoin mining pool and Bitcoin mining software.

The Bitmain Antminer S9 doesn’t run cheap – on Amazon, it’s listed at roughly $700.00,but price change happen almost daily.  But as long as your electricity costs aren’t high or are free, the Bitmain Antminer S9 will probably pay for itself in a year or so.

Of course, the time at which you’ll recoup the cost depends a lot on the
Bitcoin and Difficulty price. As new manufacturers release their own competing hardware, the price of the S9 can should fall too, But as new hardware is released, This one becomes obsolete. So be on the lookout for new realease dates and try to sell your old hardware before that happens or you can be stuck with nothing more then a room heater. The older models can also be useful to learn on and play around with.


As semiconductors become smaller and smaller, computing power and electrical efficiency have grown. However, current technology won’t allow the process to go on for much longer.

In fact, some believe that Moore’s Law no longer applies. The rate of advancement in computing speeds has slowed because it’s now coming close to the physical limitations of the silicon semiconductor tech.

The S9 does offer a nanometer technological advantage. It uses a 16-nanometer fabrication process, which is a major step up from the 28-nanometer process seen in other mining devices. However, increases past 10 nanometers look unlikely  for a while. Although you can do a bit better than the S9, the improvements are decidedly slowing down. But  new releases are coming soon with 10 nanometer preorders from another manufactured just released.


Every existing power supply with enough wattage will be compatible with the S9, making this mining device more accessible. You can run them at 120 or 240 volts.


The S9 comes with more hashting power in its silicon than any device that came before it, with 14 Terahash per second.

It uses three circuit boards and a whopping 189 chips to achieve this power. Keeping in mind that Difficulty changes each fortnight and the Power Cost depends on your location, what’s the projected profitability?

You’ll also need to factor in Pool Fees, which depend on the mining pool. The S9 packs a lot of power, but with a single unit, you’re unlikely to find any blocks from solo-mining.

Remember that the Bitcoin to dollar price constantly changes, too. This makes it hard to project profitability. If you’re considering the
Bitmain Antminer S9 Bitcoin Miner, your best bet is to use a Bitcoin mining calculator to plug in the most current numbers and find out your projected ROI
as changes move aroudn quite a bit, even daily.

Some people mine and then immediately convert their coins to regular
currency. Others believe in Bircoin’s future and hold HODL coins thinking the
price will go up. If you remember in January / December of 2017/2018 The price was $20,000 per coin.

Power Consumption

The S9 is more electrically efficient than other mining devices before it, thanks to its high-tech manufacturing process. It only uses 0.1 Joules for each Gigahash, so it’s more than twice as efficient as the Antminer S7.

The S9’s total power consumption comes to about 1,340 watts, with a bit of variance. Although it uses about 300 watts more than the S7, that’s a small price to pay for such great efficiency & mining power.

Setting Up

Except for the power supply, the S9 is self-contained. You don’t need to connect it to any other computer to get it to interface with Bitcoin nodes.

Use the easy onboard web management portal to make setup and maintenance a breeze.


The Antminer S9 features a sturdy, air-cooled design, so it’s easy to service and maintain. As long as you use it in a well-ventilated space, the S9 will perform well, from keeping a couple of units in a basement to a mining center with hundreds of thousands of S9s.

Should You Try Hobby Mining With the Antminer S9?

The Antminer S9 is no longer a brand-new device, so the hobby mining potential isn’t as great as it once was. The more that major miners put the S9 into use, the lower the profitability potential gets. However, constant changes in the Bitcoin world mean things could turn around at any moment.

That said, the S9 is an excellent piece of hardware. Using the current numbers with a calculator will help you decide if it’s right for you at this time.
