Although Bitcoin’s popularity has grown exponentially since last year, it does not necessarily mean that all countries are interested in it. It's probably that some countries are concerned that the local currency may be undermined by digital currencies or that digital currencies are used by criminal organizations.
尽管比特币的“人气”自去年以来呈指数级增长，并不代表所有国家都感兴趣，可能有些国家担心当地法币因此受到威胁，或更担心数字货币被犯罪组织利用。
