the end result does not determine whether there was a crash or bubble. all the things that went on in the middle of beginning and end will determine if there was a crash or a bubble. and as others mentioned there was both a bubble and a crash in bitcoin.
there was also lots of FUD like always and also there will be a big rise after this dip is over, like always!
This is not a crash its called volatility and we are already up for yearly. So this is called correction.
Yes we lose power cause of authorities but bitcoin will gain losses soon. its not bubble for sure.
volatility and correction are factors that apply to a much less price change than this. we had a little less than 70% drop. that is neither volatility nor correction.
I would better call it the Big Game of the greatest players on the market of cryptocurrency. I also think that it is not a correction at all. Now Bitcoin got more popularity.
