Ask HN: What is the best place to sell a domain?

I have a domain name that is coming up for renewal in the next ~3 months and I can't afford to re-register it. The domain, blockchain.iq, was bought to make an alt-currency version of Bloomberg like site. Idk if it is worth trying to sell it, but it did cost $200 to register it in Iraq and was a hassle. I've never sold a domain before:

- Is it worth it?

- How/Where is the best place to do it?

- Is there any way to guage how valuable it is?

I just want to clarify, I'm not a domain squatter, just broke.
