Can I buy a mining card
take tradition as an example, if you think soybeans will fall, you will sell the put contract, and if you really fall, you will earn. Similarly, if you think digital currency or bitcoin will rise, you will buy the bitcoin bullish contract, and you will earn when bitcoin rises
in addition to investment, the contract also has the function of hedging. For example, if you have 10 bitcoins and you are worried that they will depreciate in the future, you will buy the equivalent bitcoin put contract. If they do fall, your bitcoin will shrink, but your contract will make money, so as to achieve the function of hedging
finally, I would like to remind you that digital currency contracts are different from traditional contracts. There are four major exchanges in traditional contracts, and there are no such problems as running away and being unprofessional. However, digital currency is different, and position crossing and position bursting occur frequently. As far as I know, the margin system of Fangtu FOTA completely rivets Credit Suisse and OCC. You can refer to it
From the second quarter of this year, bitcoin based virtual currency market is very good, and the price is also rising. In the face of such a turbulent mining tide, all graphics cards are out of stock instantly, not only a card, but also N card which is not so suitable for mining has been robbed, and the price of graphics card is rising again and again. But now, with the change of national policies, these virtual currency boom bubbles burst instantly. After the mine disaster comes, the owner of mines has also sold a lot of second-hand mine cards in order to rece the loss. Most of the prices are only half of the new graphics cards, and most of the 1060 rubbish 1060 has become a reality. p>
after most manufacturers suffered losses in the mining boom a few years ago, they are much smarter this time. Most manufacturers have adjusted the warranty policy for the mine card, either greatly shorten the warranty time, or refuse the warranty for the mine card, but it is not that the mine card is relatively easy to detect for manufacturers, so at present, even the relatively new mine card warranty is a big problem, for example, if the car overturns, the after-sales cost can only be borne by consumers themselves
is it worth buying?
although the mine card has various disadvantages, the price advantage still makes many consumers, including Xiaobian, have an impulse to buy. Is the mine card worth buying? This is not a question that can be answered. In Xiaobian's opinion, it's better not to touch Xiao. Buying a new card is the safest means. But it's not necessarily for DIY players. Although buying a mine card is a matter of gambling on character, if you master the following points, you can rece the risk a lot
1. Don't buy the graphics card of three or four line brand. Compared with the first or second line brand, many three or four line brands will shrink their materials, especially for the power supply part. Under the condition of full load power consumption for a long time, the pressure on power supply mole can be imagined. In order to have stronger performance, many non-public graphics cards of first and second tier manufacturers use better materials than public ones in many parts. Even mine cards have better quality stability than those of small manufacturers
2. Try to choose brands with better after-sales service. As above, large brands are much better than small brands in terms of after-sales service and convenience. In case of car rollover, the maintenance of large brands' graphics cards should be more convenient
We know that mining is like testing the aging of the graphics card, so the service life of the card will be shortened. However, if we can select the card with a short mining time, for example, the quality of the graphics card with only about two months is guaranteed. Take n card as an example, choosing 10 series graphics card will be safer, We can also look at the purchase or proction date of the graphics card to determine how long it has been used, and then look at the yellowing degree of the core capacitor, so that we can basically determine the remaining service life of the graphics cardfor the vast majority of users, the mine card is not worth recommending, especially for Xiao users, in case of problems, the after-sales cost and labor cost are not low, and the old companies should be cautious in purchasing mine cards, but now the mine tide is receding, the price of new cards is graally returning to the normal price, and the price advantage of mine cards is not so obvious, Why not buy a new card
after years of using the card to wipe the st, it looks like new. It is not recommended to buy mine cards, which may strike at any time e to long-term high load operation.
it's better not to buy a mine card. Although it's cheap, the mine card displays 24 hours a day and is overloaded. Even if it's all right with you, the mining will accelerate the aging. It may not be long before the situation occurs frequently, until it's scrapped!
