... and I myself am holding onto 3 or 4 decent ones in that very hope...
To expand on that as it might have appeared very unhelpful...
I'll show how and why I personally have hyphenated as it might help...
I feel that the below ones of mine have very obvious use cases, where there is super high demand:
Sell-Work.com
Shop-Cheaper.com
Create-Articles.com
And as for the below ones I made sure there was an EXTREMELY close comparable WITH hyphens. This lowers my risk significantly I feel.
Cool-SMS.com (cool-sms.de sold for $2,160)
B2B-Forum.com (b2b-forum.de sold for $3,892)
Dirty-Cartoons.com (dirty-cartoons.us sold for $2,004)
New-York-Casino.com (new-york-casino.org sold for $6,075)
Your-Sex-Shop.com (your-sex-shop.com sold previously for $1,950)
For the record... I have so far never sold a hyphenated domain.
