How is it possible to buy and sell Bitcoins in china? Because as per the news, China aims to clamp down on all cryptocurrency trading with a ban on foreign exchanges.Chinese regulatory authorities had imposed a ban on initial coin offerings (ICO), a cryptocurrency-based fundraising process, and termed it illegal in China in September 2017. That ban triggered an instant 6% decline in bitcoin prices. Following the ban, the Shanghai-based BTCC bitcoin exchange was forced to close its Chinese trading operations.
It obviously increases the value to people in China. There are many families that want to take Yuan and store it in ANY other currency, crypto currency makes a lot of sense for those people.
Look at all the western media reports of Asian home buyers inflating housing markets in USA, Canada, Australia and UK. People want other things to store their wealth in than the Yuan.
If you buy bitcoin in the west and sell it in China, there is 5-10% markup, Venezuela rumored to have 20% markup.
