I really emailed vpn.com brokers,they did not confirm yet how coolmathgames.com was not sold on 1.8M$?! Still I wait their answer ...
I respect what xynames replied.
Fortunately, there is interest for
coolmindgames.com ,only I do not know what will be final price...
I read dighow.com sold for 3M$ ,april 2018,although nobody expected this sale-even godaddy appraisal is little over 1K...
It seems surprises are possible in domain industry.
I am inventor. Domains are my hobby.
xynames-thank you for your info and opinion
