The price of Bitcoin has fallen below $34,000 (£24,030) for the first time in three months, after China imposed fresh curbs on crypto-currencies.
Beijing on Tuesday banned financial institutions and payment companies from providing services related to cryptocurrency transactions.
It also warned investors against speculative crypto trading.
It follows falls in Bitcoin of over 10% last week after carmaker Tesla said it would no longer accept the currency.
On Monday the crypto-currency was down 22%, a fall of about $6,000 in the last 24 hours.
Meanwhile, other digital coins such as Ethereum and Dogecoin lost as much as 25% and 29% respectively.
At the same time, Tesla shares fell more than 3% on Wall Street, possibly due to the electric carmaker’s exposure to Bitcoin.
The firm, owned by Elon Musk, still holds around $1.5bn worth of the crypto-currency.
Beijing cracks down
Crypto-currency trading has been illegal in China since 2019 in order to curb money laundering. But people are still able to trade in currencies like Bitcoin online which has concerned Beijing.
On Tuesday, three state-backed organisations, including the National Internet Finance Association of China, the China Banking Association and the Payment and Clearing Association of China issued a warning on social media.
They said consumers would have no protection if they were to incur any losses from crypto-currency investment transactions.
They added that recent wild swings in crypto-currency prices “seriously violate people’s asset safety” and are disrupting the “normal economic and financial order”.
Neil Wilson of Markets.com said: “China has for some time been putting pressure on the crypto space, but this marks an intensification – other countries might follow now as central banks make strides towards their own digital currencies.
“Until now western regulators have been pretty relaxed about Bitcoin, but this might change soon.”
