Here is what Ver said about it:
I've never sold a single domain name in my life. I've only purchased them, and then used them.
I don't think he would ever sell this domain. It's very important weapon for him in war against Bitcoin and his ego is probably too big to sell it.
I never thought of this before until today, but the funny thing about him using that domain is the free advertising he does for Bitcoin while his sole intention is to market BCash. The same pretty much applies to the BSV camp where they are also bleeding a lot of exposure to Bitcoin, especially with how they refer to BSV as Bitcoin and not as Bitcoin SV.
People by now already know that Bitcoin doesn't cost $300 per coin anymore, or $130 in BSV's case. Too bad for Roger, the bitcoincash dot com domain is currently in possession of the BSV camp, but then again, similarly, they're doing free advertising for Roger's BCash.
