I don't think there is anything unique about Blackcoin - it's a Bitclone with PoS (old mechanism) and poor distribution (top 100 wallets control more than 53%. Wallets =/= unique people) and some rhetorical improvements ("faster than Bitcoin, blah blah")
It's currently the pump and dump. Looking back 90 days the PnD used to be mintcoin and vertcoin.
Distribution is very good considering the age of the coin. IMO, you can't really compare it to established coins. There's a limit to how much distribution is possible this early in any coin's development. Distribution improves
a lot on the way to any coin establishing itself, as the price rises. Holders get more and more tempted to sell with each rise after the tipping point. Hypothetically, if BC really has the steam and built up to $25, the distribution would look worlds better at that point. I'm fairly sure BTC, LTC and most of the big players had far worse distribution at this point in their development. There are established coins that still do.
PoS is old, yes... but there has not been a full PoS coin before. Only hybrids.
NxT is more full PoS than Blackcoin ever was (which had an initial mining phase). That being said, NxT coin died after hitting $90+ million when all the FUD about distribution brought it down.
Nobody is saying you need a distribution involving 30,000 people or 6 billion people, but nobody wants to invest into a ponzi scheme where a very small handful of people reap all the benefit.
According to the top Bitcoin wallet list, which include exchanges, there's only 700 wallets with amounts over $1 million and wallets does not =/= unique persons (it's well known that wealthy BTC whales break up their funds into multiple wallets as a security measure).
. I don't see how Blackcoin is shaping up to be any better than BTC - in fact - it's likely going to be worse.
I wouldn't bring up distribution comparisons with BTC as BTC back then had little value and it was more a hobby. In contrast, all these alternate coins are deliberately creating ponzi schemes based on the assumption their coin could hit $12 billion and the inner circle of early birds / friends / speculators will walk away with 100s of millions each.
