"Coin circle" refers to a group of people who focus on digital currency's speculation and encryption, and even issue their own digital currency fund-raising (ICO for short), commonly known as "Coin circle" in the industry.

The bill refers to digital currency, including BTC, ETH, EOS, etc. A circle is a trading circle, a circle of friends, and a social circle. Digital currency's issuance, trading, speculation and everything related to digital currency are all currency circles.

I would like to remind everyone here that the currency circle is risky and investment needs to be cautious.
