Overstock.com, founded by Patrick Byrne, disclosed in a Securities and Exchange Commission  filing this week that the holder of a warrant had exercised its right to buy $100 million worth of shares. Although the filing did not identify the investor, Byrne told CoinDesk it was the Quantum Fund, managed by billionaire George Soros.

Of the $100 million Overstock received, Byrne said he anticipates $20 million will fund DeSoto Inc., the blockchain property rights joint venture he is working on in partnership with economist Hernando DeSoto.

As for the other $80 million, Byrne said he intends to invest the funds across Overstock's flagship e-commerce platform (which accepts bitcoin for payments) and the other blockchain ventures that are part of its Medici Ventures subsidiary.

With the cost to complete a Bitcoin transaction climbing to over $30, it will be interesting to see how much business Overstock is now doing via Bitcoin.
