What are your tips on choosing domain name? .dev or .com?

Recently, I have been developing one website related to developers and already decided one name for it. So I went on the domain provider and search for that name but the .com domain is way much pricey (around $2500 USD) because it says that it is a premium domain.

Now the problem is that the people are habituated with the .com domain. There are plenty of domain names such as .net, .dev, .tech and I think the .dev is more suitable for the website since it is related to developers. Then one more question comes in mind about the future of the .dev domain.

So, What are your tips on choosing domain names when you stuck in situation like this? What should you do? Do you keep the .dev or change the website's name and use the .com? Does domain name really matters?
