Technically Proof of Stake was created by Sunny King ,
So Peercoin would be more accurate than bitcoin.
PoW is a failure as BTC has proven, China controls way more than the 51% needed to dominate it, and investors just ignore this fact.
When the Value is in the ASICS and not the coin itself , failure is eventually a certainty,
which is why PoS is currently the only viable solution to running a coin network.
FYI:
You should post a running total, because according to the article, krypton is still short more than a BTC needed to afford the swap to PoS with Bittrex.
