PeerCoin is seeing renewed interest over the last few months. If PeerCoin can break out, it may face little resistance towards previous highs around $7.5. It will be interesting to see if it breaks resistance at approx. $2.45.
PeerCoin was the first cryptocurrency to implement Proof of Stake in a combination of Proof of Stake / Proof of Work, paving way for many of the more successful newer coins.
