I was looking for the reason for .cx ccTLD and found the followings
Customer Experience
A .cx domain can be used to create a website dedicated to communicating with customers, or to show a business's commitment to providing a great customer experience.
Cryptocurrency
The .cx domain can also refer to a "crypto exchange" and may be a good choice for cryptocurrency sites.
Christmas Island
The .cx domain can be used by businesses that target residents of Christmas Island, which is located in the Indian Ocean south of Indonesia.
So the crypto exchange represents the ccTLD .cx. It's now confusing me with .ce
This just shows that there was a good marketing team promoting the idea that .cx was good for crypto businesses.
.cx has always been a top Christmas Island domain. But the similarity is with .tv - Tuvalu's top-level domain, which has become an excellent source of revenue for the country. The same thing they want to do with .cx. Some tried to sell the idea that .tv was a good domain for television channels. But, even today, there are few televisions that have adopted this idea.
People must keep in mind that these types of top-level domains continue to be references in their respective countries. And search engines continue to classify these ccTLDs as being from a certain country or for the target audience of that country.
