Last month we published the news of a Chinese cryptocurrency exchange's acquisition of ZB.com for a digital asset service. This week, it seems that another cryptocurrency company has opted to acquire a two-letter .COM as UnitedBitcoin looks to have acquired the UB.com domain name from Chinese brokerage company 62.com, who have been responsible for many two-letter .COM sales in China. Registered in 1986, UB.com is one of the world's oldest domain names, but it has a checkered past. In 2007, the domain was acquired in a silent auction for $129,420. Two years later, a company called Ultimate Bet acquired the domain, but in 2011, the Department of Justice seized the UB.com domain along with several other Internet addresses. The domain remained inactive until earlier this year when UB.com looks to have been acquired by a client of Chinese brokerage company 62.com. Just two months later and the domain is back in use, this time under the operation of UnitedBitcoin. UnitedBitcoin looks to be the brainchild of Bitcoin core developer Jeff Garzik, co-founder of blockchain company Bloq. According to information available, UnitedBitcoin is a Bitcoin hard fork that "will establish a credit currency system pegged against fiat currencies, and supporting smart contracts that can serve society, by nurturing worthy blockchain developments." It is currently unknown whether this was a full domain acquisition, or whether this is a lease-to-own acquisition. We have contacted 62.com for confirmation, but so far we haven't had a response.
