Blackcoin have already completed positive correlation waves in the past through long bursts. I expect that given everything going on in 2017 and 2018 regulatory wise plus this crypto's 2014 history, that another prolonged correlation can come soon. They have merchants already starting to accept them, are less than a dollar in price, and are trying to utilize a secure proof of stake protocol. The potential is mostly there. Also they past an inflection point and follow a recursive pattern given their past bursts. I believe even if you invested mid 2018, that it can still be profitable throughout the coming year for next target. This is medium to high risks but have a 150% potential gains possibility. (Crypto wise) Invest in your own risk.
