LOL @ zitcoins

Seriously though, bitcoins.com was probably originally bought amongst a lot of other domain names in the hope that some of them could be worth much more than they were bought for someday.  I definitely don't think the purchaser in 2000 knew what bitcoin would become, and probably thought more that maybe it could be a possible name for a money news or exchange site, or much of anything else that bitcoins could have implied back then.  Or maybe it was just a couple of words that were thrown together by someone while thinking of domain name ideas, and it sounded catchy enough.
