Blackcoin resembles Quark in that it is practically premined and its price can be decided by the preminers. Quark made the preminers rich when the premine ended and pump began, but it has been going down since taking the sheep with it. Don't buy blackcoin.
You my sir...
Risto is correct. Blackcoin will likely fail because the initial distribution of coins was economically inefficient and will not be perceived as legitimate by the larger cryptocurrency community.
For developers interested in experimenting with PoS coins, consider using the "spin-off" technique:
https://bitcointalk.org/index.php?topic=563972.0The "spin-off" technique is a method to distribute an initial pre-mine based on the distribution of unspent outputs in the bitcoin blockchain at a pre-defined point in time. This bootstraps the coin with the largest potential user base and results in a coin distribution that is known to be efficient for bitcoin.
