Estimates on how much bitcoin.com would fetch on the open market?
He leased / rented it a few years ago for something around 10k/month, but the people who leased it were garbage at running a website / business and he took it back.
As for the value I don't think he will sell it and doubt he'll put a value on it.
Please can you share the history of bitcoin.com domain? I am really interested how Roger get his hands on this domain and somehow curious, why theymos and people behind bitcointalk.org / bitcoin.org didn't get that domain.
On another hand OP, it doesn't matter much what was website's history which was built on bitcoin.com domain if Roger plans to sell because this is top domain. Just check yourself keyword "Bitcoin" in google keyword planner and you'll see the results. So domain bitcoin.com worths millions and if we consider the fact that it's news website, these news worths money too and it adds extra price to it but domain alone still rocks.
