Maybe, at first when bitcoin was in its "infancy" everybody would have this claim. Today as we see some big companies like as Microsoft, Dell and Virgin Galactic are pretty happy to accept bitcoin as payment for their goods and services without consider many small stores and e-shops. Moreover there are so many people have their savings in bitcoin that seems to me will already have their own research about bitcoin. To summarize bitcoin is a reliable strong global currency even there is not mass adoption but sure is not a pump and dump crap coin.
Because if we analyze it carefully, The price has been increasing until reaching the current levels, it is true that along the way there has been an infinity of p&d or at least that's what it seems, for example recently, I not know if you remember very periodic increases and decreases in the range of +50 -50 in the prices, now it seems to have stabilized a little more, then and recapitulating, even though you're actually right BTC is strong when compared to the rest, so although some people dump it, this eventually will recover as long as there is the demand that has been submitted up to now, but as time passes, this question will be further defined.
