I just found out that the domain bitcoin.uk is still available, and can be registered!

The only requirement is:
the registrant or the address for service for second level domains must have a country code of GB, GG, JE or IM

Well,

Hurry up i suppose!

Hi everyone!  

I am working on a URL shortener to meet all the necessary and useful features: https://shorten.club  

Features:
- your link can be direct, framed, or splash
- custom alias
- Password Protect (you can set a password for private linking)
- Geotargeting  
- Easy Sharing
- Statistics
- public & private profile
- Bundles
- You can choose between 2 domains (We will be adding more soon.)
- It is Bitcoin friendly
- free registration (you can use it without registering)

Here it is https://shorten.club


Here is a list of exist url shorteners and most of them lack  of these features.
