It is funny that you had this project in mind for maybe, 3 hours before you realized that you wanted to do focus on another project.

When i looked at the whois for the .biz domainname (i didnt want to waste more time and look at the rest).

It said:
Domain Registration Date:                    Mon Nov 25 00:26:06 GMT 2013

http://www.whois.com/whois/shopwithbitcoins.biz

So you clearly registered the domains to sell them.
You are fully allowed to do that, but some people (like me) think its a bit shady. (it stops people that actually build things from building them, thinking someone else is working on it, when its just a domain name broker.)

And so do you, otherwise you would have wrote: i registered them to sell them to a person who want to develop this idea.
Instead of lying about your intentions.


Happy Auctioning.
