Choose the best domain registrar

When we need to buy mangoes we fall into the trap of thinking which company we will be more profitable to buy from and which company we are loyal to. There are thousands of design companies in the world who provide domain services to any part of the world through their websites. But the question is which company will be the best to buy the domain from? You can answer the question well
And the answer to this question depends on how you use the domain
1. You buy for a short time ?
2. You will buy for a long time ?
3. Is your website permanent ?
4. Is your website temporary ?
5. Is your website serviceable and you don't want to make any money from it ?
Think for yourself what kind of work you want to buy a domain for.
Got the answer, if you want to use the website for a long time and make money from the website then you have to think about the security of the domain without considering the price. Because without security you can never manage your website for long. If you want to buy for a short time, it is better to buy considering the price. Take it from where you get the demand at a lower price.
If you are running a website for a service, you can get a domain at a lower price.
But before buying a domain, one thing to keep in mind is how much you will have to pay next year as the price of the domain.
