The easiest way to find Available Domains is by typing locally, that is... if you live in Brazil and want a domain in Portuguese, your chances of finding an available domain are much higher than international domains.
We know that the whole world speaks English, so the chances of finding domains available in this language are smaller, however, they are domains that, in theory, have more value, essentially if you use words well-placed in the Address such as: diet, money, brokerage, losing weight, health... you know?
Domains with these names are more difficult to find available and if you find them, the Prices are also higher, after all, they are much easier to remember, don't you think? So the tendency is greater for you to have direct traffic.
Some NFT Domains are almost free, prices are usually very low, especially if you use numbers and rarely used extensions like .dao, .888 or .zil. Ex: crypto10s.zil. This domain costs only U$ 5... Extremely cheap, especially if we compare it to the traditional web domains here.
