Is Bitcoin Mining Still Profitable in 2021?

What is the best bitcoin miner in ? Well there is no straight answer. So how do bitcoin miners choose which rig to buy? Here we will fill you in. In this article we compare the thirty most profitable bitcoin miners of , and then discuss issues with popular models. We end this piece by taking a look at off-brand ASICs, as well as not yet released bitcoin miners. Read more about how to be a bitcoin miner in our previous article. Here is a table of the 30 most profitable bitcoin mining rigs on the market in We rank these top ASICs by their net daily profit.

Scroll down for variable information. The daily electricity cost is also represented by a percent of the gross profit. Efficiency , shown to the right of the table, is a ratio of watts joules to terahash. Read more about bitcoin miner equations here. Models are sorted by manufacturer and popularity as follows: Antminer, Whatsminer, AvalonMiner, and Innosilicon. Other manufacturers including Ebang, StrongU, and Bitfury are discussed in the following section.

Be aware that the information here is based on personal experience, miner reviews, and hearsay. Bitcoin ASIC batches and models can vary widely in quality and performance.

So we recommend that miners take this information with a grain of salt, and follow-up with their own research. This allows Bitmain to mass produce Antminers with optimal efficiency ratings. However, Bitmain has been criticized for delays and inadequate quality controls. Ultimately Yang appealed and the court decided that the patent design was widely used in the industry. So far the Antminer series are known to be reliable and profitable. Institutional miners have ordered hundreds of thousands of units.

S-models are thought to use the best quality chips from a wafer, whereas the T-series use slightly less stable chips. Why is this?

Well, when a wafer is created in a foundry some microchips have imperfections. The percent of good dies is referred to as the wafer fabrication yield , see the image below. Whilst mobile phone companies and other tech industries bin bad quality chips, bitcoin ASIC manufacturers deploy them in lesser efficient models like the Antminer T A common complaint with the S19 and other Antminer models is that they automatically shutdown when the ambient temperature is too hot or cold.

But this feature protects the hash boards and can be worked around with environmental controls. S19s may also break after sudden power outages.

This was experienced by some miners in China in the wet season when dams cut electricity to release water load after heavy rain. Although Bitmain recommends to pull the power plug to shutdown a machine, other miners suggest shutting it down in steps to prevent chip damage from residual heat. However, miners believe that the S17 and T17 reflect poorly on Bitmain. The main issue is that the microchips and heat sinks can loosen and detach.

Also, temperature sensors can fail. These problems are attributed to bad quality lead-free soldering, and cheap thermal adhesive. The knock on affect of this issue is that when a machine has poorly attached heat sinks the warm air does not dissipate away from the microchips.

Chips can burn and hash boards can fail. As shown in the Best Bitcoin Miner in table above, the series is still very profitable. Yet these models require frequent attention, and some mining farms refuse to host them. Luckily specialists can rework bad soldering and glue. Further, replacement parts for the series are available because many were produced.

But keep in mind that hash boards are only interchangeable between the exact same model. For instance a S17 hash board is not compatible with S17 Pro. Lastly, it is likely that a considerable amount of S17s and T17s suffered heat damage from previous owners who ran overclocking software, or who ran turbo mode on the S17 Pro. Thus secondhand units may break more easily due to harsh wear and tear.

The Antminer S9 series is not included in the table of the Best Bitcoin Miner in , but would rank in at about 70th place. It is estimated that millions of S9s were produced between For the most part these machines are sturdy and reliable , but after years of running many are coming to the end of their existence.

Additionally the S9k, released the same time as the S17, is reported to have trouble with bad soldering and glue. On the other hand, home miners and hobbyists still appreciate the S9 model because the electricity draw is less than half of the newer S Home miners can also pick up S9s cheaply and use them to learn how to undertake repairs or autotune chips.

The M1-M3 used 28 nm chips, and the M10 machine employs Samsung 16nm microprocessor chips. In the end Yang was released without charge, and rumor has it that the two companies settled. Between MicroBT also experienced some delivery delays. These were contributed to Covid, increased bull run orders, and supply chain bottlenecks.

Note that the M21, M31, and M32 are less energy efficient than the M20S and M30S models, presumably due to lesser quality dies, or the use of 10nm versus 8nm chips. They do not break down often , and they are very popular with miners.

Institutional miners have placed years worth of orders. Due to the higher electricity draw, miners sold off M21S models in the bear market because they ran near breakeven. But thanks to the current bull run, M21S models are profitable again. Lastly, the other issue with Whatsminer is that hash boards are not widely available.

So if a hash board fails, it may be impossible to replace. Whatsminer do however have service centers in three locations worldwide, and have some components like replacement M30S chips for sale on their US website.

For those who are unsure, FGPA stands for field-programmable gate arrays. ASICs on the other hand are custom made to order in foundries, and are not programmable. Uniquely, Canaan has multiple chip suppliers which they claim speeds up production. Overall AvalonMiner are very reliable and robust machines. Institutional miners have placed huge orders. The A is in the top ten of the Best Bitcoin Miner in list. Like Whatsminer, AvalonMiner takes more energy per terahash than an Antminer.

Albeit Avalons are known to be a strong machine which can be started at lower ambient temperatures. Avalons are also known to use good quality cooling fans which may help them to perform better in climates which are humid, or which have high condensation due to cold weather.

Further, they are reportedly easy to repair. Luckily, PSUs can be replaced. For hash board failures Canaan will send a replacement so that miners can install it themselves to minimize downtime. Also, Canaan supplies miners with updated firmware to autotune chips with high temperature readings. For the miners who report low hash readings, Canaan apparently stated that the hash difference was within an acceptable range. On the contrary, many miners report no issues with the newer Avalon models and are pleased with their investment so far.

Thus, problems seem to only pertain to certain batches. One review found that the A ran in the hash range stated over a 24h period. This built-in encryption algorithm in the main control chip helps to prevent viruses and theft.

The other issue with AvalonMiner is that spare parts may not be as readily available as they are for Antminer, as less are produced. But spare parts may be more available than Whatsminer, as Canaan have multiple chip suppliers. Lastly, as with most ASIC manufacturers, the main customer service center is located in China, so shipping for repairs can be timely and expensive.

They also opened a service center in Kazakhstan this year. This particular miner is not on the Best Bitcoin Miner in list but gets an honorable mention. These machines are still profitable and sturdy, however they are coming to the end of the line as they are now three years old. Innosilicon were established in Yet the company has not released a new generation bitcoin miner since Regardless their machines are still considered reliable and sturdy. Innosilicion use 10nm Samsung chips in their bitcoin miners.

This year Innosilicon released a few different versions of the older-gen T2 Turbo, but these were not efficient enough to make it to our list of the Best Bitcoin Miner in Notably, the model has anti-skid pads on the underside to reduce friction and secondary rust on rack equipment.

Issues with this manufacturer are minor. For example, one miner found that the fans were mounted the wrong way around after delivery. This resulted in high internal temps and low hashing speed, but was easy to fix.

The company are known to have good customer support.

China crypto mining ban triggers exodus, bitcoin rigs sell like scrap

Bitmain Technologies Ltd. By postponing sales, it could help miners exiting the industry get better prices for their machines. Bitmain could also benefit if the reduced supply buoys prices over the longer term for new machines. The firm said it will continue to sell gear for future delivery of devices used to mine smaller altcoins. A company spokesman confirmed the decision, which was reported earlier by local blogs, without saying when business will resume.

Why China Is Cracking Down on Bitcoin Mining and What It Could Mean for Other Countries

Bitcoin mining plays a pivotal role in the Bitcoin network. Miners act as the backbone of the entire Bitcoin network, upholding the security of the network while ensuring nobody cheats the system. Antminer S9i is currently the best Bitcoin mining hardware available on the market.

In a time where the world is struggling to manage the covid pandemic, rising global crisis, unstable political clime, and social environment, cryptocurrencies have shown just how dogged they are even in the face of economic uncertainties. While the global pandemic-induced economic downturn has been a blessing in disguise for the crypto space as it attracted many professional traders into the space, it has also revived interest in mining as a lot of people explored different ways to generate passive income. For instance, in regions like Abkhazia, where the government has banned all crypto-related activities, terming it illegal, there has been an overwhelming demand for mining machines. Bitcoin , the number one cryptocurrency by market cap, has risen by almost a third.

Idan Abada is on a mission to democratize bitcoin mining. As far as he's concerned, minting new coin isn't just for the pros. The post has since gone viral on TikTok, with 2. The rig looks a whole lot different than a warehouse packed with rows of whirling ASICs — an image which has come to be synonymous with crypto mining. Everyone can become a miner and be a part of the crypto world. Abada started mining bitcoin in his room in a shared house in — where he agreed with roommates to pay extra for electricity — and in , he opened up his own shop. Abada says his business has grown exponentially in the last four years, as interest in crypto has ballooned.
