http://www.coindesk.com/overstock-reports-over-100k-in-bitcoin-losses-for-q1-2015/Speaking to CoinDesk, Overstock cryptocurrency group general manager Judd Bagley indicated that the loss was primarily the result of declines in certain altcoin markets in which the company has invested.
"The swing in the value of our cryptocurrency holdings is attributable to the sale of some of our non-bitcoin cryptocurrencies, the use of some of our bitcoin to pay for services including our membership in the Chamber of Digital Commerce, and changes in the market," he said.
He went on to clarify that the company "holds more than just bitcoin", but did not clarify which digital currencies Overstock has invested in.
Bagley stated that, in its quarterly filing, the holdings are considered a part of the same asset class.
"We’ve invested in other cryptocurrencies over time, and for the purposes of the SEC filing, we lump them all together," he continued.
