China’s market is one of the largest in the world, as well as its crypto coin market. when many coin holders are forbidden to use their coins, they sell their coins in panic, and those outside of China who hear them also plunged in the FUD. In the end, the sudden rise of supply of a sudden made the price of Bitcoin immediately fallen and FUD became worse
Well, I would say the market WAS one of the largest but no more. Sure, China really had a great influence on bitcoin as so many of the population quickly embraced it and a whole lot of them have been mining from the start, which is why we would see most of the largest mining rigs in China today. So, we will just have to give them that.
However, since the government has probably used that to create lot of FUDs, and they once had the largest market, then obviously from the look of things, there is no one or country that is indispensable and the next available markets obviously over took them.
