The CME and CCOe bitcoin futures index futures for February 2018 also fell below 9,000 US dollars.
The price of other virtual currencies, such as ethereum, ripple, bitcoin cash, and litecoin also declined.
The drop in prices came after a statement from Indian Finance Minister Arun Jaitley. Jaitley's remarks raised fears of an increase in virtual currency-related regulations in India.
In addition, The New York Times also proclaimed that many investors are worried about the price of bitcoin and other virtual currencies have been enhanced by the exchange of Bitfinex.
Currently, some investors believe that bitcoin prices will move in the range of 9,000 to 10,000 US dollars.
Level 9,000 US dollars is the lowest level in two months.
"A lot of rumors about regulation make the market panic," said Nick Kirk, quantitative developer and data scientist at Cypher Capital.
In his speech, Jaitlet stated the Indian government did not recognize the virtual currency as a legitimate payment instrument.
The government will also take steps to reduce the use of crypto assets in the funding of illicit activities including criminals.
Data Coindesk shows, ethereum price reaches 1,051 US dollars, 1.281 US dollars of cash deposits, and litecoin 143.28 US dollars. The ripple price reached 0.99 US dollars.
