I think I will hold on to this domain for a while and make something of it Thx for all the feedback. I am somewhat new to website/domain flipping and every little bit of advice helps. feel free to continue to post any advice or what you think about the domain name
Ah right, not what I had in mind when seeing the game. Then again, I play poker. Pocket aces are the best starting hand in hold'em, so "flipping aces" would make sense and is actually quite brandable.
I have www.flippingace.com up and running still have alot of development to do of course check it out if you get a chance and leave feedback!
