What does the cryptocurrency circle mean, can anyone explain?

The so-called cryptocurrency circle is a community formed naturally by digital currency players. The cryptocurrency circle is not large, but the number of people is not small either, and it basically belongs to a niche group among the crowd. Nevertheless, it is still a circle, with not many people making money, and various ways of making money have been quickly copied, such as ICOs, trading coins, mining, etc. #BTC #以太坊走势
