Coins and tokens suffered a ‘Grinch’ sell-off this weekend. Bitcoin, Ethereum, Solana, Cardano and pretty much every major digital asset was lit in red on Monday in a mix of ‘risk-off' trading and likely pre-Christmas profit-taking from the long-term crypto ‘whales’. In other news, the Bitmart crypto trading platform has been hit by an estimated $196 million hack, according to reports over the weekend. Funds were taken from the accounts of many of its customers by hackers.
