Recently, the price of Bitcoin has continued to decline once below the 6,000 dollar mark, the mining boom has obviously subsided, the hardware equipment supply chain is the first, graphics card manufacturers face the market supply and demand reversal, inventory level of the rapid rise in the recent dispute to start a bargain war to go to inventory, is expected to decline in July price will reach 20%, while the ASIC mining machine , the apparent impact of TSMC, creativity and Zhiyuan, such as Taiwan, originally expected 2018 revenue growth fear convergence. Mining boom led GPU graphics and ASIC chip and other supply chain performance soared, graphics card manufacturers March shipments and high profit innovation, April market conditions, a sharp turn, the graphics market into inventory full hands and the price of the situation. Graphics manufacturers said that the recent bitcoin has fallen below 6,000 U.S. dollars, and the impact of virtual currencies such as the etheric currency plunge, coupled with the main chips concentrated in the hands of a few people, as well as fraud spate events, investment risk increased, retail investment has been unprofitable. As the bitcoin balance points in the 6,000~7,000 dollar, the current mining benefits are no longer, small and medium-sized miners gradually exit, large miners also slow down the excavation strength. The graphics manufacturer points out that before March 2018, graphics market in short supply, March shipments are more innovative high, but the April bitcoin, such as virtual currency collapse faster than expected, medium and large customers pull strength weakened, the small miners buy gas completely disappeared, plus the graphics card has been large, the power of buyers will be weak, the graphics card shipments greatly reduced. In the face of heavy robbery in the first quarter, as well as buying gas monthly cooling, the factory is in inventory full hand status, the current global graphics card inventory estimated at least millions of, Nvidia hand also has millions of GPU continued to plug the goods, and the miners are afraid of second-hand video card to reverse the goods, the factory was forced to reduce sales. However, the graphics card is still far higher than the price of a year ago before the speculation, the game players do not want to hand, in the next quarter without NVIDIA, Ultra Micro (AMD) new effect plus hold, the video card market bargain storm has been predictable. Nvidia to go to inventory, will launch a large distribution and price, to their own and customer inventory down to the safe water level, the next generation of TSMC 12 and 7 NM process 3 of the GPU will be formally launched, the expected new volume will fall in the 4th quarter after. GPU Ore machine buy flustered frozen, overall impact nvidia, Ultra Micro Camp performance, the industry estimated that the 2nd quarter of the display card manufacturers to reduce the range of about 20~30%, of which, the ultra micro-competition in the market has little influence, video card shipments, as to include Asus, Gigabyte, MSI, shake the News, EVGA, seven Rainbow, Sotec, Sapphire and other manufacturers, graphics card shipments and profits will also significantly decline. 2018 years the next half of the graphics factory will gradually return to the demand for electricity mainly market conditions, 2018 shipments can only be flat, profit is expected to be better than 2017, but with the low tide of digging, graphics card manufacturers if unable to compete market, 2019 years of performance fear to go downhill. Mining demand for the Fever also makes the ASIC with Bitcoin as the main purchase gas greatly reduced, possession of the global 90% ASIC chip wafer foundry market accounted for the TSMC, originally expected to benefit from the ASIC mining machine, such as the Continent big single drop bag, plus nvidia new generation GPU volume, the annual revenue is expected to grow 10~15%, However, the previous law said that it would have been repaired to 10%. Manufacturers expect orders to be halved, ASIC chip OEM orders are far less than expected, coupled with the Apple iphone and other high-end new machine sales prospects unknown, the TSMC July Law said it would be afraid to reduce the annual increase in revenue. As for the world core, creativity, Zhiyuan, Moonlight, and only a few days before the signing of the cooperation agreement with the Power Crystal Group, the performance growth will not be as expected. In addition, the three major ASIC mining machine manufacturers Jia Nan Yun-chi, billion and bit mainland have an IPO plan, recently Jia Nan Yun-zhi and billion states have been submitted to HKEx, and the mainland has not yet selected in Hong Kong or overseas IPOs.
