Shares of cryptocurrency- and blockchain-related companies fell in early trading hours Monday after Binance halted its bitcoin withdrawals for several hours due to heavy volumes and rising processing fees.
The halts pushed bitcoin, the world's biggest cryptocurrency, down 2% to a one-week low of $27,900.
Crypto exchange Coinbase Inc. fell 3.6%, while blockchain-farm operator Bitfarms Ltd. dropped 5.1%. Crypto miners including Riot Platforms, Marathon Digital and U.S.-listed shares of Hut 8 Mining declined between 5.3% and 6.6%, tracking lower bitcoin prices.
Binance, the world's largest crypto exchange, shut bitcoin withdrawals for an hour late on Sunday and for about three hours on Monday, saying there was a glut of pending transactions because it hadn't offered so-called miners a high enough reward to log the trades on the blockchain.
The company said its set fees did not anticipate a recent surge in bitcoin-network gas fees - the payments made to crypto miners whose computing power processes transactions on the blockchain.
"There were so much traffic congestion and also the gas fees were so high over the weekend ... even by historical standards," Oppenheimer's Owen Lau told Reuters.
Binance said in a tweet that the company had adjusted its fees to "prevent a similar recurrence."
In March, it had suspended deposits and withdrawals citing tech issues.
