BlackCoin (BLK)

What above said. LONGEVITY. Black has first mover position and historical record of facts Do you even stake? Also low inflation, great network stats.

I have collected and never sold them since 2014 because I like the POS principle and stake myself. The community (on gitter) is not about quick profits and they carefully select improvements thanks to the work of janko33 and others. Still undervalued…

First Proof of Stake coin made with great community and good future. Big gainer for sure!

In my opinion, blackcoin is by far the best proof of stake coin in existence.
