.expert is a "new" TLD meaning that the operator can do more or less whatever they want and is not bound to the same ICANN rules as the gTLD operator(s) are. IMO nuTLDs are not appropriate for anything except joke sites.

> For example use.expert would cost me around 40-50$ per year. I mean its 3-4$ per month so I am happy with it but still, my point is that I absolutely know more domains which I wish to buy but it would just be an hassle long term. I can probably sell them at cheap auctions to recoup the price but it just doesn't feel that worth it to me but overall, yeah.

Well yes, that's exactly why we unfortunately need to pay rent for domains - otherwise speculators would just buy them all up even more than they already do.
