“A BTC craze is sweeping China, as hundreds start to invest and trade large amounts of the virtual currency Bitcoin. The craze has given birth to a huge industrial chain, covering trading, mining, chip production and mining-machine assembly. Bitcoin transactions are secured by servers called bitcoin miners but based on the huge surge in demand for the currency, Bitcoin mining machines are in short supply. According to Tencent, there are two Chinese mining teams capable of processing large amounts of Bitcoin transactions. Figures show that China now boasts the most number of BTC nodes, which help control the computing power of the Bitcoin netweek, at 85,220.”
