The bitcoin exchange says that over $ 30 million has been stolen in cryptocurrencies

One of the largest bitcoin exchanges in the world has claimed that more than $ 30 million of cryptocurrencies have been stolen.

Bithumb, an exchange based in South Korea, stated in a notice on its website that all customer deposits and withdrawals were suspended while reviewing the situation.

The warning did not say how the theft of 35 billion won (32 million dollars) of cryptocurrencies occurred or which were taken.

The exchange said it will offset the loss from its funds and that all customer assets have been "safely saved" in the company's "cold portfolio".

Bithumb apologized for the interruption and said he will announce more information in due course. The company did not immediately respond to a request for further details.

It is the latest in a series of thefts reported by the trade in cryptocurrency in recent months.

Just last week, another cryptocurrency exchange in South Korea, Coinrail, said hackers stole about 30% of their virtual currencies.

South Korea emerged last year as one of the world's leading markets for bitcoin and other virtual currencies.

According to the CoinMarketCap.com website, Bithumb was the sixth largest cryptocurrency exchange in the world by trading volumes in the last 24 hours.

The news of the theft to the exchange has hit the prices of cryptocurrencies. Bitcoin fell 2%.

Analysts say that many virtual currency exchanges are vulnerable to hackers because they have grown rapidly without implementing sufficiently strong security.

In January, Coincheck's Japanese exchange said that hackers stole more than $ 500 million of cryptocurrency. In the past year, two bitcoin exchanges have failed after falling victim to similar violations.
