This is much easier to remember. The cx TLD is too hard to remember as I already posted in my last post.
.cx it's not hard to remember, it's just unusual, so it may require an additional check of the correctness of the domain name. .pw (which was used at some point) is perhaps a worse choice because it is cheap and often used for one-off scams and malware distribution
.net is my personal favourite, and I will be glad when it is officially the default domain for exch exchange.
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
