Yes, you are right. But I would not choose completely unverified domain registrars. Because it often happens like this: you register a domain at a low price, and then during the renewal it turns out that the prices will be too high. I have chosen the Pananames registrar 2 years ago. Everything is clear with prices here. Moreover, the prices for the renewal are scheduled for many years ahead. I also use hosting offered by the registrar. The prices are quite adequate. Everything is fair and there are no unexpected price increases.
