Lisk recently experienced 2 slight bubbles, those bubbles were based on promise hype. Currently Lisk is very simple version of Bitcoin, nothing beyond that. We do have delays on rebranding and 1.0.0 release. SDK has been planned on Q4 2017 but seems it will be also delayed. I think now it's time to short and then around 50-60k satoshi entering back again. Beginning of new year or end of Q1 2018 might be time when they release SDK.
