The digital currency breached new highs before falling below $14,500, down 14% on the day according to Coindesk.com.
Bitcoin had soared about 70% this week, with its dramatic rise being likened to a “charging train with no brakes”.
As concerns mount, an industry group has warned plans to start Bitcoin futures trading have been “rushed”.
Critics have said Bitcoin is going through a bubble similar to the dotcom boom, but others argue it is rising in price because it is crossing into the financial mainstream.
“Bitcoin now seems like a charging train with no brakes,” said Shane Chanel, from Sydney-based ASR Wealth Advisers.
The surging price of Bitcoin has been helped by the start of trading on the Chicago-based Cboe Futures Exchange on Sunday. The world’s largest futures exchange, CME, will begin its Bitcoin offering a week later.
Trading on futures exchanges allows investors to buy and sell contracts for the crypto-currency at a certain point in the future at an agreed price.
But the Futures Industry Association, which includes Wall Street’s largest banks, brokers and traders, has written to the US regulator over concerns that the contracts were approved “without properly weighing the risks”.
“A more thorough and considered process would have allowed for a robust public discussion among clearing member firms, exchanges and clearing houses,” the association said.
While Goldman Sachs is a member of the association, it is also one of the banks that will work as an intermediary to help clear Bitcoin futures contracts for some clients.
A spokeswoman for the investment bank said it was evaluating the risks as part of its due diligence process.
Many big investors have been reluctant to pile into the crypto-currency market unless it is regulated.
However, the prospect of a Bitcoin futures market has raised hopes that it will be regarded as sufficiently “regulated”.
While Bitcoin has become more mainstream in recent weeks, many observers warn the market could be a bubble waiting to pop.
“Bitcoin remains a major gamble as it is very much an asset that remains in uncharted waters, we’ve simply not experienced this before,” said Nigel Green, founder and chief executive of deVere Group.
“An asset that goes almost vertically up should typically raise alarm bells for investors.”
Even a crash or a major correction is unlikely to pose risks to the global economy, some analysts say.
While billions of dollars have been invested in Bitcoin, its $268bn total market value is still small compared to other asset classes
