Great name, you just never know with domain hacks. Could fetch $50k+ to the right buyer. I would definitely hold onto it and wait for the right offer. You could even develop the domain into a portal for GPT sites.
They have said that about every non dot-com extension. But domain hacks are proven to be popular especially if it is a common word like "dollars" with a lot of end-user potential.
In my opinion, you shouldn't wait for a buyer to find you, you should go and to active outreach to potential end users.. Like @sdsinc said, most domain hacks never sell so if you plan on waiting, you can wait forever.. But with active outreach you actually show the name to potential buyers as most are probably not even aware that this domain would be an option for them.. Start with the .com buyer
