As far as I know there is no bitcoin.com its bitcointalk.org I not pretty much sure about it but so far I didn't heard about it.
There is bitcoin.com and it doesn't really support bitcoin now as it's shifted and more focused with their own fork altcoin which is bitcoin cash as stated above, owned by Roger Ver.
Don't visit that website and warn your friends who are newbie to bitcoin, it is deceiving the newcomers for telling bitcoin cash is the real bitcoin which is very wrong.
Bitcoin is the only real, genuine bitcoin and there's no any other coin that is real bitcoin.
