"Solving Bitcoin's Centralization: NXT vs Clam"
https://www.youtube.com/watch?v=WMZqnbtzXOISummary: Bitcoin failed to remain decentralised due to it's proof of work design. Proof of stake is biggest innovation in crypto since invention of bitcoin. NXT and Clams are great POS coins but for very different reasons with very different risks. Now that altcoins are at an all time low these are great buys in my opinion.
