Well tell us why bitcoin survived 2013 and why its so much different NOW, yea we hit 500-20k instead of 100 to 1100 once, and? longterm upward movement is still clearly there you can fud like this if we fall under 1k again
Bitcoin investors who have been some time around just wait for sign of live ( like breaking some support lines which indicates upward movement ( specially with high swings because of FOMO..), once the train started again they all hop in again.. specially if we have like once doubled and so on and bitcoin reaches the news again for example..)
Bitcoin have those huge swings because people are unsure what will happen but it doesnt matter if -/+ 80% or -/+ 5% like in stocks it just needs to happen or it would be a "superbubble" ( in my opinion )
bitcoin was not in global awareness in 2013, icos were unknown in 2013. there where no useable encription services. like ethereum back then.
it will get even worse once the indexation and market definition issue gets decentralised.
