Bitcoin, one of the most popular cryptocurrencies, has been trading at around $2,800 per coin.
That is now down to $1,700.
But Bitcoin is now worth around $3,600, according to a recent report from the crypto-currency exchange Bitstamp.
It is currently trading at $1.5074, according the data provider Coinmarketcap.
CoinMarketcap estimates that Bitcoin is worth around 5.7 billion US dollars at the time of writing.
The cryptocurrency was worth $2.4 billion in late 2017.
The digital currency has seen a dramatic rise in value.
On Wednesday, the price of Bitcoin rose to $2.,099 per coin, according Bitcoin analyst Matthew Greenfield.
This is a drop of almost 90 percent from its current peak of $4,829 per coin on November 20, 2017.
This may indicate that the cryptocurrency is beginning to sell off, Greenfield said in a tweet.
The crypto-coin is up about 10 percent over the past month.
According to Coinmarketcoverage, Bitcoin rose by 7.6 percent in the first half of 2018, while it also gained by more than 5 percent during the same period last year.
