Stellar appears to be decoupling. In Stellar's history these trends do not last long. They often predate a big move for either BTC, or STR/XLM. My assumption is we will see some added volume in Stellar, and see the price raise slightly higher before either a BTC rally, or a Stellar fall will recouple the two. But there can be no better opportunity to make free coins than to take advantage of these types of conditions.
Keep a sharp eye traders!
