Are used miners or new miners better for Bitcoin miners?

Regarding Bitcoin mining, there is a question that most miners will be concerned about: should Bitcoin mining choose a new mining machine or a Used miner?

The advantages of choosing a used miner are obvious: the cost of a used miner is much lower than that of a new mining machine, which will speed up the return cycle of mining; however, the quality of the used miner varies, and shoddy ones abound, and there may be large risks of.

The disadvantage of the new mining machine is that the price is relatively expensive and the payback period is longer, but the machine is brand new, the quality and lifespan will be more guaranteed, it can be mined for a longer time, and the frequency of maintenance is much lower than that of the Used miner, per unit time income is relatively high. Between high cost and high risk, how should miners choose?

Where does the used miner come from?

There are two main sources of used miners: one is the replacement of old and new machines by miners on a large scale, and the other is the migration of electricity price resources. Miners with high energy efficiency ratios flow from miners with high electricity prices to miners with low electricity prices.

The circulation of the used miner market is also mainly divided into two channels: one is the circulation between big miners, which is the trading mode of acquaintances; the other is the trading mode of strangers, first, a very small number of people who can contact the primary source of used miner, a large number of used miners The miner first flows into the hands of those who have the right to speak, and then flows through them to the Used miner dealers, and then from the dealers to the miners of all sizes.

What should be noticed when buying used miner

As the market changes, some miners will replace their old machines with new ones for the considerations of revenue, security and operating costs, hence the used miners come in. Miners may choose to buy used miners due to the consideration of cost performance or the inability to buy suitable new mining machines. However, the purchasers of used miner should pay attention to the following problems, to avoid from fraud.

•To buy from a legal company

The channels of used miners are very complicated. Miners should purchase used miners from companies with a track record of long operating time and good reputation, negotiate with it the transaction and after-sales terms, and clarify the responsibilities and obligations of both parties so as to safeguard their rights and interests thereafter.

•After-services are available

When trading used miners, the seller will generally make the promise of "Guarantee for hashrate and installing on the rack". "Guarantee for hashrate" is the promise of the used miner, and "guarantee for installing on the rack" is the promise of the normal operation of the mining machine after installing on the rack.

It is an industrial rule for the sales of mining machines, that unless there is a very serious quality problem, no return is acceptable. Generally, when trading mining machines, buyers can't see the real objects, and the quality of used miners is more difficult to grasp. Therefore, the promise of "Guarantee for hashrate and installing on the rack" is very important to buyers.

•Used miner under warranty

Some used miners are relatively new and still in warranty period (“under warranty” in short). The price of such used machines is also relatively high. Check the SN code of the machine to find the remaining warranty period, this method can verify the seller's statement on the machine.

In addition, attention should also be paid to the mining machines under warranty that, in such cases as disassembly, assembling, swiping unofficial firmware, etc., the rights and interests under warranty will disappear, and the official franchiser will charge high after-sales fees for the maintenance of such machines. This should also be paid attention when you buy the second-hand machines. Do not buy mining machine at guaranteed price if the rights and interests under warranty disappear.

If you want to buy a Used miner, you should choose to cooperate with a mining machine distribution company with a good reputation and a long time in operation. Such companies are more expensive to damage their reputation and reputation for a single business, and they cherish their feathers more. For example, LLGO also has a small number of Used miners for sale, and miners in need can contact them.
