BK Group Chairman Kim Byung-kun was named an executive of the Cornerstone Networks. He will serve for the next three years.

The Cornerstone Networks made a public disclosure that it would add cryptocurrency and blockchain business to the list of businesses it would pursue.

The Networks will deal in cryptocurrency exchange, cryptocurrency investment, advisory services as well as blockchain platform development and cryptocurrency payment services.

It is speculated that Kim, as an executive of the Cornerstone Networks, would bid again to take over the Bithumb exchange.

Last October, the BTC Korea.Com announced that it would sell its Bithumb exchange at $400 million by transferring 50 percent of its stocks plus one extra stock. The buyer, Kim, has failed to raise 200 billion won to take over Bithumb by March. The deadline was reset on October.
