Well, the slump didn’t last long.

This week saw Bitcoin hitting its lowest price range since July, after China’s central bank ordered companies to stop selling new cryptocurrencies to raise funds, a practice commonly known as initial coin offering (ICO).

The People’s Bank of China deemed ICOs as illegal and prohibited digital token financing and trading platforms from converting the cryptocurrencies to fiat currencies and vice versa. The tokens were also barred from being used as currency on the market, while banks in the country were told to stop offering services to ICOs.

The ICOs offer tokens that are based on the ethereum network, which means that the ban may not directly affect bitcoin. However, the news resulted in the price of bitcoin dropping to $4,200 on Tuesday—its lowest since July.
