"Domain for free" is it just a free registration?

Question

Domain name market

Then still pay for the renewal?
Or is it just a gift?

Answer 1

Yes. Moreover, most often you have to pay for renewal more than the cost of a domain with some partners. That is, for example, a partner has a domain of 90 rubles a year, that is, 180 rubles for two years. And the hoster has a free first year, but the second year renewal, for example, costs 360 rubles.
There are other disadvantages, such as security.
