The decline is due to growing concerns over regulatory measures and bans on cryptocurrency operations and was exacerbated by Monday's Wall Street meltdown.
Bitcoin plunged 20 percent on Tuesday, hitting its lowest level in three months amid the financial turmoil caused by Wall Street's historic fall on Monday.
The cryptocurrency fell to $ 6190 for the first time since November, Bloomberg reported, after having reached $ 20,000 in December.
The digital currency, which appreciated more than 1,300 percent last year, has almost lost 50 percent so far in 2018, as more governments and banks reinforce caution about these operations. Last week, it suffered its biggest weekly decline since 2013.
The drop is due to growing concerns over regulatory measures and prohibitions on cryptocurrency operations, such as those applied by US financial giants such as JPMorgan Chase & Co and Citigroup in the fear that lenders could be held responsible for massive losses in case of a crash in the value of the cryptocurrency.
Central banks in Europe, Japan and the United States also expressed concern about the currency, while India said on Thursday it would take "all measures to eliminate" the use of cryptocurrencies as part of the payment system and to finance illicit activities.
The plunge of bitcoin was exacerbated by the huge losses in world markets, with the Dow Jones on Wall Street that wiped out the gains of 2018 in one day.
At present the bitcoin is rising a bit, we hope it stabilizes but it is time to buy cheap bitcoin and then sell it expensive.
