Billionaires are embracing crypto in case money 'goes to hell'

Even as prices swung wildly, investors large and small dived into Bitcoin and Ethereum as well as non-fungible tokens

Thomas Peterffy took out a full-page ad in the Wall Street Journal in 2017 warning of the dangers that bitcoin futures posed to capital markets.

These days, the Hungarian-born billionaire is well versed in cryptospeak. Peterffy, worth $25 billion, said it’s prudent to have 2 per cent to 3 per cent of one’s personal wealth in cryptocurrencies, just in case fiat currency goes to “hell.”

He owns some himself, while his firm Interactive Brokers Group Inc. recently offered customers the ability to trade Bitcoin, Ethereum, Litecoin and Bitcoin Cash, after detecting “urgency” from its clients to get in on the action.
