Bitcoin domains are not in demand right now. Wait 2 years and then sell. Right now people will give you something like 0.01 btc for a domain like bitcoinforstuff.com .
They are in demand, if the domains are good enough then they will sell.
The only problem is that people are asking too much money for mediocre / poor domains.
@ OP
Just list your domains for sale, don't listen to what others say. Good luck!
