Blackcoin is an established coin. It will not die that easily, it isn't certain that it eventually reaches much bigger adoption. It is still striving for that, but people should try to understand it is easy to get somewhat established the push beyond that is much much harder. Use the coin for purchases or trading and wait for the bigger developments like BlackBox, Nighttrader and Blackwave Labs. These projects can't be rushed and they can't magically appear in a few weeks or months.
