You just exactly described my relatives who signed up on coinbase during the peak in a panic and asking me for advice. "What is litecoin? Should I buy this? Will it keep going up so I can double my money? What is bitcoin cash? Should I buy? Werent you in that before? What is Ethereum? Should I buy? Woah wtf is happening to btc? Im down. Ok I just bought ripple. Can you explain ripple to me now? This isnt working. I need you to trade for me."
lol
I kind of see now why we rushed from 10k to 19,5k and then went suddenly down again
it did that for the same exact reason why it rushed from $3000 to $7800 and then suddenly down again to $5400 (November 2017)
oh wait it is not done yet. the same reason was again when it rushed from $2000 to $4900 and suddenly down to $3100 (September 2017)
you thought i was done? haha big mistake.
the same reason repeated when price rushed from $890 to $2700 and suddenly down to $1800 (May 2017)
haha, i can go all day long with the same reason when price rushed from $450 to $778 and suddenly down to $550 (June 2016)
and finally from $200 to $470 and back to $360 in November 2015
we even had the same reason back in August 2012 when price went up from $6 to $16 and suddenly dropped to $10
i let you find these and more on the charts yourself...
call it FUD, manipulation, fluctuation, pump and dump, bubble, newbies FOMO/PANIC, whale shenanigan, winter is coming, bitcoin is dead, bitcoin is king, normal market movement, natural adoption curve, blah blah! it doesn't make any difference. that is what has been happening forever.
