Heist appears to have shaken markets, with bitcoin, ethereum, and bitcoin cash all falling.

LONDON — Major cryptocurrencies bitcoin and ethereum are falling against the dollar on Tuesday morning after a $31 million heist elsewhere in the digital currency world.

Tether, which created a cryptocurrency called USDT that is pegged to the dollar, said in a blog post on Tuesday that "funds were improperly removed from the Tether treasury wallet through malicious action by an external attacker."

$30,950,010 was taken in total on Sunday, the US company said.

"As Tether is the issuer of the USDT managed asset, we will not redeem any of the stolen tokens, and we are in the process of attempting token recovery to prevent them from entering the broader ecosystem," Tether said.

Tether is down 0.3% against the dollar on the back of the news, according to CoinMarketCap.com.

The theft appears to have shaken wider confidence in crypto markets. Bitcoin is down almost 1% against the dollar at 7.45 a.m. BST (2.45 a.m. ET): bitcoin
