Seems ETN is at the stage of a major shakeout. They want the price to dip so low everyone gets discouraged and sells their coins.
I don't think this coin is going to fail. It seems too big to fail. However, it can stall out for sure. This has happened with most top coins in their infancy. A huge rally followed by a lingering total capitulation that results in huge sells only to be bought up in stealth by large accumulators.
