By the end of 2020, the blockchain technology has evolved into a global market worth $990 billion. Although Bitcoin is still the most popular cryptocurrency out there, hundreds of new cryptocurrencies have appeared, among which Ethereum sticks out the most. In the beginning, Bitcoin was a token that anyone could mine with a GPU, however, when ASICs (application-specific integrated circuits) arrived, mining Bitcoin and other SHA-256 coins with the GPU became pretty much pointless.

Some cryptocurrencies, like Ethereum and Monero, are resistant to ASIC mining as they use completely different algorithms that are optimized for GPUs. This, however, frequently causes massive GPU supply shortages, as both consumers and miners compete for available graphics cards. Running a profitable cryptocurrency mining business in such environment can be really though, since supply can’t meet demand, and you are forced to miss potential profits due to limited amount of available mining tools.

ASIC mining, on the other hand, doesn’t have such problems. Different ASIC miners are always available for purchase, and can be easily found at major online marketplaces such as Amazon, Newegg, or Coin Mining Central. Besides Bitcoin, ASIC miners also let you easily mine cryptocurrencies such as Litecoin, Dash and ZCash, and are often much more profitable than GPUs (depending on the Bitcoin price). In recent years there have also appeared new ASICs (FPGAs) that feature GPU components, and thus enable you to even mine Ethereum and Monero.

In this roundup we’ll show you the best ASIC miners that are currently available on the market. When choosing the right miner for your mining setup, you should pay attention to the miner’s hashrate (mining performance), power consumption, supported mining algorithm, and price. High-end miners usually cost a lot, but are also able to deliver great mining performance, and steady financial income. Cheap ASIC miners are usually good for mining beginners, as they are able to deliver decent daily income alongside satisfactory power efficiency. Some ASIC miners are even more optimized for specific algorithms, such as Kadena, Equihash, or Blake256, so be sure to check them out if you are mining specific cryptocurrencies that use such algorithms.
