Hello @huascargarcia, I see very good this shorten URL and earn money! I think it would be a little bit to share my links and earn a little money seems perfect.

These are the pro that I could find:

Pro

• a great and clever website
• allows you to register quickly
• give users the opportunity to shorten any URL in a shorter URL
• It is free to use
• Payment in crypto currency
• Have CRM systems to check the URL data

Cons

I did not find any

Keep up your big hunt, good luck :)
