How to decide what hardware to buy?

There are three main factors you should consider when picking which ASICs to buy other than budget. The first two factors is profitability and return on investment (ROI), profitability is calculated by taking the value of the mined coins minus the cost of electricity and ROI is calculated by taking the cost of the ASIC divided by the daily profitability to see how many days it will take for you to break even on your investment.

The third factor to consider is what coin the ASIC can mine, Bitcoin ASICs are valued higher than other crypto miners because we know they will continue to produce profits for years to come while other smaller coins may become much less profitable over the next few months/years.

Top 5 ASIC Mining Machines:


1. Bitmain Antminer S19 Pro


Hashrate: 110Th/s – Power usage: 3250W

Coin: Bitcoin – Cost: $9,799.95 – $12,999.95

Profitability: 7/10 – ROI: 6/10

Notes: The Antminer S19 Pro is the most profitable Bitcoin ASIC miner. This is a great choice if you want an ASIC you can be sure will produce relatively high profit for many years to come.

2. GoldShell KD5


Hashrate: 18.7Th/s – Power usage: 2250W

Coin: Kadena (KDA) – Cost: $9,499.95 – $14,999.95

Profitability: 10/10 – ROI: 8/10

Notes: The GoldShell KD5 is one of the most profitable and highest ROI ASIC miners. Only downside to this ASIC is it mines KDA which is not a top coin, you can however exchange or sell the KDA after you mine it.

3. Goldshell CK5


Hashrate: 12Th/s – Power usage: 2400W

Coin: Nervos (CKB) – Cost: $6,499.95 – $10,499.95

Profitability: 8/10 – ROI: 7/10

Notes: The GoldShell CK5 has very high profitability and ROI at a cheaper price point to the KD5. Only downside to this ASIC is it mines CKB which is not a top coin, you can however exchange or sell the CKB after you mine it.

4. Innosilicon A10 PRO+


Hashrate: 750Mh/s – Power usage: 1300W

Coin: Ethereum (ETH) – Cost: $14,799.95 – $17,999.95

Profitability: 9/10 – ROI: 8/10

Notes: The Innosilicon A10 PRO+ has very high profitability and ROI while also mining a top crypto coin. Only downside to this ASIC is Ethereum will most likely be moving away from using miners sometime in 2022 but after that you can mine a few other profitable coins.

5. Bitmain Antminer S9


Hashrate: 14Th/s – Power usage: 1320W

Coin: Bitcoin – Cost: $849.95 – $1,299.95

Profitability: 3/10 – ROI: 5/10

Notes: The Antminer S9 is the cheapest BTC ASIC you can get that still produces a profit at moderate electric costs. This is a great first miner to get started and learn how to operate ASICs as a side business.

Honorable Mention: Bitmain Antminer S17+


Hashrate: 76Th/s – Power usage: 2920W

Coin: Bitcoin – Cost: $3,799.95 – $6,299.99

Profitability: 5/10 – ROI: 6/10

Notes: The Antminer S17+ is a great mid tier ASIC if your budget is in the $4,000-$6,000 range.

Where is the best place to buy ASICs?

There are two main options for buying ASICs, ebay or third party retailers. Ebay is not recommended because you’ll have to weed out all the shady sellers and pay a huge scalper premium.

If you go with a third party retailer like us you’ll have the peace of mind you’re buying from a reputable company at fair prices since we’re able to get a huge bulk order discount from the manufacturers.

Should you buy new or used ASICs?

Deciding on buying new or used depends on what you value more, new machines will cost more so they will take longer to break even but will last longer making you more total profit in the long term. So you really just need to ask yourself if you want a higher ROI in the short term or more profit in the long term.
