Possible for registrar to speculate domain price by holding it?

I just wonder lately that is there such a possibilities that a domain registrar could actually registered domains in bulk when user perform search using their tool, but didn't registered the name on the spot. So would it be such a "possibilities" that the said registrar actually register the domain and "put" it in the inventory waiting to be re-sell at higher price?

Well, in this way, the said registrar is actually driving up the price and make a large profit isn't it??

Haha. I don't know if this is true... but I will tell you a little secret.

Whenever I have the idea for a new domain name, I will not type into a search engine, I will not type it into my registrar nothing. Not until the time I am ready to pay for it. Only then will I actually let anyone know about it. I guess even then a shady registrar could steal it from me when I went to pick it up... but have had no problems.

I am sure I am just being paranoid.

I've often wondered about this ...when I've thought of a possible good domain name, and researched it, I 've always had that little doubt about privacy ...so I don't think you're paranoid at all!
