Keep the NP$ for another year, and I reckon that they will be worth 50% more.
ATM, you will get a rate of around $0.018:$1NP. So, atm your NP is worth more than $234, in 1 year that will have grown by more than $117 to $351.
The $NP is amazing. A whole currency has been created online, and is even stronger than some currencies belonging to rich countries. Makes me really amazed.
