ShadowCash has slowly increased in value over the last two years, but within 48 hours there market cap jumped from 2.5 million US to +4 million US, amazing. ShadowCash is now worth $0.63 USD per SDC, with Poloniex holding 86% of SDC's volume. There's lots of hype with there two year anniversary, and the upcoming release of Shadowmarket and Shadowchat. If the dev produces Shadowmarket and Shadowchat, we could see ShadowCash running a lot longer with the bulls.
