Why is BC better than PPC?
Why i should invest in BC instead of the father PPC?
PPC has estable prices and also a good potential of growing, also what makes BC different from Mint or ECC?
The answer is: it isn't better, in terms of potential Returns on Investment.
The reason is, contrary to BlackCoin, PeerCoin destroys all transaction fees. This makes the yearly inflation of 1% irrelevant, since the suppy tends to remain the same (not counting with mining).
BlackCoin doesn't destroy transaction fees, so it has more inflation than PPC which means in long term there will be always some correction because of this inflation.
But still, BlackCoin is great coin and 1% inflation / year is nothing.
