I mean, you can't compare real estate with domaining, it's very niche, highly speculative market (and maybe not so ethical, there is a thin line that separates domainer from cybersquatter).
You shouldn't act like a douchebag for anyone...
I'm bothering with crypto escrows, educating potential buyers, bothering how all this crypto stuff might look for an average Joe in negotiations...
Meanwhile people just chit chat in poor english and scam each other at WhatsApp, fantastic
Yes, I've found them while searching crypto escrow services, but don't consider them as a domain marketplace in the first place, they are definitely not the first option to buy a domain, they're not popular in this niche,
But you won't lose...
