You have other domains. Someone else has offered at least that much money to the TLD for the domain. Unfortunately you’ll have to monetize that domain you love or let it go to the market. Donain names are real estate. If someone sees you have a lot of traffic they’ll raise the price.
Put a banner up notifying folks of whatever new domain you point your site to over the next few weeks.
Good luck to you
Without knowing the domain name, we don’t know what the original classification was.
