When investing in a Pos currency you should not just look at the% that it offers per day / month / year. This is because otherwise you go hunting for the highest gain but then high inflation destroys the currency itself.
In the Pos currency, in my opinion, it is really important and fundamental to look at the project itself, the support team and community, the technological innovation it offers, if it is unique and different from the others.

Respecting these criteria above I believe that the best Pos currency coins today, for growth and potential, in order:

Deep Onion (Pos 10% First Year)

Xspec (Pos 5%)
