Unlike other cryptocurrencies, the Bitcoin hashing function and consensus mechanism do not incur any ASIC resistance; that is why ASICs have disrupted the entire bitcoin mining ecosystem in no time and made graphic processing units unviable in bitcoin mining. In short, ASICs are the fundamental mandate to begin bitcoin mining. However, people who are currently interested in investing are in doubt whether it is now too late to invest in bitcoin and discussions are available online.
Since the advent of ASICs on the market in 2014a, bitcoin mining has gone through a complete shift in its fundamental value and has started to serve as an investment rather than a commodity. Even though miners can buy the latest NVidia and AMD graphic processing units (GPUs) to mine bitcoin, they do not profit significantly since ASICs can outperform GPUs by several folds. The dilemma is how long GPUs will take to become obsolete in mining. Here is a list best ASIC bitcoin miners.
What is an ASIC miner?
Miners are special-built computer chips that, at present, only mine bitcoins. These units have been the sole developers of Bitcoins, and they currently control the currency supply. An ASIC miner is a device that holds the ASIC chip and connects to the internet, enabling you to receive bitcoins created by this machine.
The latest range of Bitcoin ASIC miners can also have a use case in mining other cryptocurrencies based on SHA 256 algorithm (for example, dogecoin). ASIC is an application-specific integrated circuit. They are designed for a particular function, such as Bitcoin Mining.
Each person has a role in verifying each transaction when a BTC is being transacted within the community, which is said to be “mined.” When these transactions are verified, they are projected onto what is named “block,” and it becomes part of an encrypted chain stored on your hard drive or computer memory.
The whole Bitcoin process and protocol runs on the network. All computers connected through this network compete and work together to solve math problems known as algorithms (Mining).
#1) Antminer S19 Pro:
Overall, the S19 Pro is the most economical and best choice for a fast and effective mining rig with a small size for your miner. This miner is powered by a 2.4 GHz processor, which can deliver up to 110 fps of performance when calculating at the speeds of 14-nanometer complex technology. In addition, the AntMiner S19 comes with a 150-watt power supply, which is top-notch for products such as this.
Its single ASIC chip delivers the hashing speed of 14.7 nanometers, almost twice what you expect from miners like 13.5 N.M while using less electricity. However, the Antminer S19 product is a significant size as you require at least 3 case fans to provide adequate airflow for efficient cooling inside the case and to prevent overheating the machine during operation.
#2) WhatsMiner M30S++
The WhatsMiner M30S is the more advanced version of WhatsMiner M30, a bitcoin miner introduced by the manufacturer in November 2017. It is the best ASIC machine for mining bitcoin with less power consumption and heat output.
By giving you a hash rate of 70 Th/s, this machine will consume only 1.9 KW/h even though it is powered by 28nm chips which deliver superior performance compared to other miners that are being used in the market. A hash rate of 112 TH/s will give you a return of 0.007 BTC per day on an initial investment as low as $3999.
#3) AVALONminer 1246
The Avalonminer 1246 miner is a great product introduced by the manufacturer Avalon in March 2017. It is one of the cheapest ASIC machines for bitcoin mining, coming in at $4047 with a hash rate of 180 Th/s. Even though it produces less power than other products like Antminer S15, this miner will still be able to produce 0.95 BTC per month with a power consumption of 1600 watts and using the same amount of money for its power requirements that you pay monthly for your air conditioner.
#4) AvalonMiner 1166 Pro
Avalon miners are best when it comes to high hash rate mining. Therefore, they can easily dominate the bitcoin mining industry with heavy-duty miners. The AvalonMiner 1166 pro is a product introduced in 2015 and is one of the most popular miners in the market.
It comes with an overall hash rate of 110 TH/s, along with an initial investment lower than $3999, making it an ideal choice for all who want to start mining bitcoins without spending too much on expensive ASIC machines like Antminer S9 or Antminer S15.
#5) Ebang EBIT E11++
Ebang EBIT E11++ is an excellent miner powered by a 16nm process, making it one of the most powerful miners on the market. It comes with an overall hash rate of 190 TH/s, which falls into a category known as mid-level miners. Its initial investment of as low as $3999 will produce 1 BTC per month.
The AntMiner Z9 Mini is one of the cheapest and most efficient ASIC machines for mining bitcoin, with a high hash rate that you can find in the market today.
