Don’t forget The Toolbox, plenty of great url shorteners found on that page. 

How much are you selling cut4.cash for?

There have been claims that cut4.cash does not count all views (source), however your ANN thread claims you do count all views. Why are you selling your shortlink service, do you have any intentions of fixing what is wrong with it before handing it off to someone else? What is your asking price? I hope you fix the not all views being counted problem before someone decides to buy your website!

do not promote this site when you are selling it!  https://bitcointalk.org/index.php?topic=2630368.msg26765484#msg26765484

it's absolutely not fair, people start add your shortener to their pages, some1 will buy and the website owners needs to rework all of their pages!

Already started to work =D 

If you're paying only for unique views, you're going to have to raise the CPM dramatically to compete with the other shorteners.
I've got other paying providers that easily average twice of what you're offering.
If you pay for all views you'd be just right with the CPM.
Maybe go for a compromise? Pay for the first 10 views from 1 ip?
