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.
You don't seem to realise that "Once you go black you don't go back" is a well known phrase that been used for a long time before Blackcoin existed. It's not something that Blackcoin made up. People aren't supposed to guess the ending.
