Something that scares me regarding domain names is their variable cost. I purchased a .sexy domain for a joke website and its price got raised by +70% less than one year after that, making the joke a lot less appealing. There’s no guarantee that when you purchase a domain name it reasonably stays around that price for years.
Build a business on a domain -> the name increase by XX% -> you’re screwed and must pay.
