Short term - because of Nubits

Long term - because its the father of POS, it's the oldest POS chain,  it has sensible developers who are playing the long game,  not just trying to be the next gimmick pump as all the scamcoins out there are.  

Next to Bitcoin it is by far my favorite coin and has been for a long while already..   I don't think it gets the attention it deserves.
