According to news from Bloomberg

The digital currency hedge fund was started by Matthew Goetz, who worked at Goldman Sachs for 11 years, and Ari Paul, a portfolio manager who oversaw risk at the University of Chicago's endowment office.

The capital raised comes from family offices and other institutions such as venture capital firms. Among its backers are said to be Union Square Ventures and Andreessen Horowitz.

The article also cites a Morgan Stanley report saying that there are about 100 cryptocurrency-focused funds with assets totaling to more than $2 billion. That's about $20 million NAV per fund on average (though the skew between the higher value and lower value can be quite large).

The fund also hired a former vice president at Goldman Sachs as its head of strategic partnerships and business development.

It seems like this is all the rage these days. Bankers quitting their jobs and starting their own cryptocurrency funds.
