Impressive price movement. One thing I'd like to chime in about is I really hate the catchphrase "Once you go black..." that's plastered on promo posts. It doesn't do any clever wordplay, it just leaves a juvenile thought hanging mid-sentence. I'm supposed to finish it myself in my head, I guess, with "you don't go back" or "you're a single mom" but if you wanted to go with a stupid cliche for advertising some kind of twist on it would be better than the lazy way out of making people finish it themselves.
BlackCoin - Welcome to the Dark Side.
There are a few sports teams in the US that portray a bad boy image, one that goes against conventional thought. One example is the Oakland Raiders and their uniforms are largely black. I think the color black represents this image much like pirates of old. It is appealing to a large part of US society and could be leveraged to have people invest in this coin.
One visual example would be a pirate's chest full of booty. That booty, of course, would be BlackCoins.
