To me a clear wyckoff accumulation in the volume signature. But again, my main fear at this stage is the fuckers who may aquire the remaining mt. gox BTC any day now or week could in theory go dump it on the CEX/open market. but far worth the risk as they would be shooting themselves in the foot at this stage given bitcoin is acting as an inflation hedge narrative but in 2018 spring it was definitely a different time/mood/narrative.
