Seems like it is working out to me. There have been plenty of POW coins that haven't worked out too.
POS is better for long-term energy efficiency sustainability. Put all the money your would pour into mining equipment into buying more coins, and you help raise the value of your prior investment. Coins don't wear out, like any mining gear will. And you can always resell if if you want, but but mining gear depreciates. The coins are the miners
what ever floats your boat, Ive just seen this so many times before
See:
Blackcoin, Mintcoin, Reddcoin, Zeitcoin, Asiacoin etc etc ... the list is pretty long of these games played on the newbs, have fun dancing around the musical chairs.
You might want to consider...variations of pos
ethereum is aiming at pos variation - hence eth classic will follow im sure
nem i think is a variation of pos.
steem was but failed because mostly it was an instamined scam like dash and has been dumped hard.
I think variations of pos will in future take the lead.
I don't think pos or pow is a big factor to success or fail. Unless you know more than VB, SK, Rat4 and larimers. These are some of the best coders and designers in this field.
