There are people from every fraction of the community (The one who does the research, the newcomers and the one that never got a hold of cryptocurrency) saying that Bitcoin is a Pump and Dump and a Bubble for a reason. History tend to repeat itself and the graph shows and replicates what happened in the past(Tulip) but we can never know the future. Maybe it's the time and Bitcoin is the revolutionary evolution and it may Pump and Dump but it wil never bubble. Or it will at some point. We can only hope for the best.
