http://www.devtome.com/doku.php?id=a_massive_investigation_of_instamines_and_fastmines_for_the_top_alt_coins#blackcoin
The author of this page didn't do anything except scan the blockchain. Apparently knew nothing about the history, devs or great community. Yes, there was a pre-mine but it was announced, it was open and at least a thousand of us were mining millions of blackcoins during the pre-mine. Active devs like rat4 (PoS, PoS 2.0), David Zimbeck (BlackHalo smart contracts, NightTrader) and Blackwave Labs (Blackbit, Ruby Wallet, BC-centric Exchange) continue to work this coin.
Yet your official topic said "no premine". this smells even more like a huge coverup for a scam.
BlackCoin had no premine, and also the analysis you cited doesn't claim that. Every initial distribution model of a PoS coin happened in a short time, in BlackCoin through a short PoW phase. People quickly use the term "instamining" which is actually a term for PoW coins with a ridiculous block halvening policy.
The current distribution of BlackCoin is better than in most alt coins. Regardless if you think that BlackCoin is a good investment or not, you will hardly find a second PoS coin code base that contributed so much to the cryptocurrency community. Several coins in the voting are BlackCoin forks btw.
Pandacoin's distribution phase was 95 days long. 95 days of fair mining during our POW phase.
So, "every distribution model of a PoS coin" did not happen in a short time. Ours didn't.
That's why Pandacoin is the fairest and most secure PoS coin in the world.
