Tiger 21, a network of ultra-high net worth investors and entrepreneurs, holds around $6 billion in digital currency

Odaily News Michael Sonnenfeldt, founder and chairman of Tiger 21, a network of ultra-high net worth investors and entrepreneurs, said members of the network collectively hold about $6 billion in digital currencies.
“About 1% to 3% of our $200 billion in assets, or about $6 billion in assets, is in cryptocurrencies,” he said in an interview on Wednesday. “It’s still very exciting. We have some members who are all in. It’s become a gold alternative.”
Sonnenfeldt also said: "Gold is for traditionalists, and Bitcoin has new-age characteristics, but they generally play the same role and are both seen as a store of value." (CNBC)
