Personally, I see Blackcoin as a fucking instamined gimmicky sponger!
Remember the tons of shit thrown on quark for the 6 months instamine...? Well, what about BC with its one-week instamine..??
But everybody's jumping in, and mint too... wtf?!
As for good coin, i suggest to take a look at Myriad, NO premine, 5 indipendent algos that allow to mine it with whatever, asic, gpu and cpu.
i found this on reddit and i totally agree:
vert alienates asics and CPU miners but was innovate so took off. So what is going to happen with a coin that gives everyone an equal footing. This is what satoshi intended for bitcoin but could not predict the impact of asics and slowly this week the community is waking up to the fact.
