Cryptocurrency-related domain names continue to increase in value as interest in bitcoin and other digital currencies skyrockets. The most valuable site on the market may be ethereum.com, which can be purchased for $10 million and already has a $7.2 million bid. While that is the high-end there are several hundred cryptocurrency-related names selling around $1,000, up from just a few dozen last year. Some of the biggest recent sales include: Cryptobank.com ($125,000 in April), Cryptonews.com ($50,536 in August), Bitcoincash.org ($48,888 in July) and bitcoin.casino ($28,000 in March). “The unfettered euphoria I see around bitcoin/cryptocurrency/blockchain reminds me a lot of the atmosphere I saw in the period preceding the dotcom bust around 2001,” said Ron Jackson, publisher of Domain Name Journal.
