LTC is just an imitation of BTC but PPC is a completely different cryptocurrency. I'm not promoting the coin but the idea of Proof of Stake (PoS) is just genius. Not only does it save energy that could've went to other meaningful and productive calculations but it also gives coin generation power to every coin holder ANYWHERE he/she may be in the world. Homeless people, uncivilized tribes, etc. would have a fair and equal coin generation capability.

I wanted to mine bitcoins before but my country is really far away from those ASIC manufacturers. I didn't want to risk my money to pre order hardware. I believe Satoshi Nakamoto created bitcoins to give anybody with a computer generate significant amounts of bitcoins. From what I am seeing today, that is no longer the case. Bitcoins are no longer completely decentralized. Eventually, the people who has the most mining power will rule it. Many may not share this view especially those people who have access to the new ASIC miners. I trully believe that PoS in coins is an innovative solution for the geographical problem. Mining will become the fundamental problem with bitcoin. It is unsustainable, wasteful, volatile, easily manipulated by strong enough players, geographically selective in terms of hardware availability and electricity rates. The author of the article makes great points against altcoins but is incredibly biased on bitcoins.
