Bitcoin.com was first registered on September 19, 2000 by a swedish company, Hurricane Communication AB. (Hurricane Communication AB - Gothenburg, Sweden)
Between 2000 and 2008, Bitcoin.com was forwarding to the web site of a South Korean technology company, IVN Tech.
On January 4, 2008 the owner was Jesse Heitler - Denver, Colorado. Bitcoin.com dropped eventually, and it was re-registered in 2008. At the time, the registrant’s name was Jesse Heitler, according to historical WHOIS data from DomainTools.

Regardless of how much money Roger Ver paid to acquire Bitcoin.com, that price would be eclipsed, thanks to the BTC value today. Roger Ver is the CEO of Bitcoin.com and owns its domain name now.
I wonder if you'd find more data, just don't forget to leave here.
