In the previous article "What are the pitfalls of buying mining machines? "Attractive" futures mining machines", we mentioned that it is actually difficult for retail miners to buy mining machines directly from the official website of the mining machine manufacturer . Compared with these large miners and mining machine dealers, retail miners need to pay a lot of costs when purchasing mining machines, such as higher prices, later delivery times, full prepayment, etc. Today, let’s talk about one of the costs that retail miners pay when buying mining machines: the unavailable mining machine coupons . 01 Mining machine coupons, like many other commodity coupons, are issued by mining machine manufacturers and can be used to deduct the amount of mining machine orders. Currently, the most famous and most circulated mining machine coupons in the industry are those issued by Bitmain, and other mining machine manufacturers rarely issue them. Generally speaking, mining machine manufacturers will give mining machine coupons to customers in the following three situations: 1. Mining machine delivery time is delayed When Bitmain signs a mining machine purchase contract with a customer, there will be a 10-day exemption period for the delivery time. For example, if the contract is signed for delivery on September 30, Bitmain can deliver the goods on October 10 at the latest. If the goods are not delivered after October 10, Bitmain will compensate the customer according to the theoretical income of the mining machine, and the form of compensation is often to send mining machine coupons. For example, according to the current mining difficulty and coin price, the theoretical net income of the Ant S19 mining machine is 34.82 yuan per day (the electricity fee is calculated based on the market custody price of 0.23 yuan/kWh during the flood season). If the mining machine is delivered after the exemption period, 34.82 yuan should be compensated every day. Delays in the delivery of mining machines are very common in the industry, but it is rare for mining machine manufacturers like Bitmain to compensate for delays. 2. The quality of the mining machine is problematic If there are defects in the quality or design of the mining machine, some mining machine manufacturers will also give coupons as compensation. 3. The market crashed and the price of mining machines was too high At present, the mining machine manufacturers mainly sell futures mining machines, and the price of futures mining machines is set according to the current market conditions. However, "a day in the cryptocurrency world is like a year in the real world", the crypto market has been rising and falling, and is full of uncertainty. If the market conditions are very bad when the futures mining machines are delivered, the spot mining machines will be reduced in price a lot, which is equivalent to the futures mining machines being sold at a high price before. At this time, the mining machine manufacturers will also give corresponding coupons as compensation. Taking the Antminer as an example, at the end of December 2019, the Ant T17e mining machine was reduced in price because the market conditions were very bad at the time. Bitmain issued mining machine coupons with a face value of 1,315 yuan for each customer who had previously purchased futures mining machines. After the market plummeted on March 12 this year, Bitmain also gave coupons as compensation to customers who purchased Ant S17+ and T17+ mining machines between mid-February and the end of April this year. 02 |
