Cryptocurrencies dropped after the second South Korean exchange in as many weeks said it was hacked, renewing concerns about the safety of digital-asset trading venues.
Bithumb, ranked by Coinmarketcap.com as the world’s seventh-largest crypto exchange by traded value, said on June 20 that hackers stole about 35 billion won ($32 million) and that Ripple was among the coins taken. The exchange halted cryptocurrency deposits and withdrawals, said it will compensate victims and moved investor assets to a so-called cold wallet, which is disconnected from the Internet and less vulnerable to theft.
