The difference between new and used machines is that new machines come with six months to a 1-year warranty. Typically, mining rigs can run for up to 5-7 years. Second-hand machines are out of warranty, and you will have to pay for repairs.

Yes, mining the cryptocurrency Bitcoin is legal in the United States.

Hash rate measures your computational power to mine and process transactions on the Blockchain like Bitcoin and Ethereum. The more hash rates a mining rig has, the faster it mines Bitcoin.

Your miner's warranty begins when KMining picks up your miner from the manufacturer.

We advise customers to read the terms of each manufacturer's warranty for more information. You can find the link to each manufacturer's warranty using the following links:

Once your miner is online at a hosting facility, a member of our mining concierge team will provide you with your machine serial numbers. If you have purchased a Bitmain and or MicroBT ASIC, you can use these serial numbers to check the remaining warranty period on your miner using the following links:

1.You will need to purchase Bitcoin mining hardware. Bitcoin mining requires specific hardware. This hardware is often referred to as a Bitcoin mining “rig”. When bitcoin first began, you could use ordinary computers to mine Bitcoin. Due to the popularity and how complex Bitcoin’s proof-of-work algorithm has resulted in the necessity for increased computer power. The hardware used by most miners is called ASIC (application-specific integrated circuit) chips. These are very powerful rigs built to solve the Bitcoin algorithm.

2.Once you have your Bitcoin mining rig, the next step is to download the necessary software to connect you to the Bitcoin blockchain. The software distributes work to miners and adds new blocks to the blockchain. Several free software programs can be used to mine Bitcoin. . Nice Hash is one example.

3.Individual miners cannot compete with large mining farms backed by large mining companies. Bitcoin mining pools are a solution for individual miners because they can combine their computing power to compete with the larger miners. Fees are paid to the pool operator, and the rewards are slightly lower, but using a mining pool will ensure that rewards remain frequent. Poolin, F2pool, Slush Pool are popular bitcoin mining pools to check out. 

KMining provides a simple calculator on each product page to calculate a rough estimate on the return on investment per machine. Many factors come into play, primarily as time extends into the future.

Your ROI calculation should include factors such as the difficulty factor/adjustment, the price of bitcoin, and the depreciation/value of your miner. All of these factors are variable.

Some customers use ROI and profitability calculators online. Here are some examples of profitability and ROI calculators our customers use:
