Hello friends,
Please, help me to decide if it's worth or not to have additional country specific domain?

I think its good for your business, your business can improve its online identity and you can protect your brand from fierce competitors

It depends on you.

.cc is a country-level domain for Cocos Islands.

If you belong to that country, you can purchase it without a doubt. If you are from any other country, don't buy these domains and waste your valuable money.
Buy a professional domain. Ex: .com, .org

There are a lot of providers with affordable costs. Check over there.
Try to start with the professional domain.

It is up to you and what you want to achieve through your business. Whether or not it's worth having a country-specific domain depends on your optimization of the website. Here are some of the factors to consider:
1. Target audience
2. Local search engine rankings
3. Brand consistency
4. Technical considerations
5. Analyze the audience's behavior.
