BitsharesX is one of the very few coins that is truly deflationary at this point in time. A lot of coins claim to be deflationary... cough... Bitcoin... but they will be inflationary during our life time.
I am 100% with the OP, PoW is not the best solution to decentralized consensus any longer due to numerous reasons.
Not during our life time? Not sure how old you are but In 1.5 Yrs time, Reward will drop to 12.5 BTC per Block, 4 years from then 6.25 BTC per Block And half again 4 yrs from then, I beleive within 10 yrs, if BTC holds its ground or even gets more ground, Demand will overpower the amount coming from rewards, which in turn = Deflation.
