Several people thinks that falling price of bitcoin is manipulated by some people, well i guess so, and i also think that more probably reason of bitcoin's price is the continuing panic selling volume coins, the price would be affected if several panic sellers do this.
Really the WRONG question is being asked here, the first question is-was "Was the parabolic rise of bitcoin in the year 2017 orchestrated?"
The answer is YES, hell yes, there wasn't a press in CHINA not telling people in June 2017, to 'buy bitcoin', to the moon, all over the world people saw btc go from $1k to $21k during that year, was it orchestrated, promoted? and the HODL, to keep the bag-holders holding,...
Now we all pretty much know who raised the price of btc, it was the whales, the winkelvoss holders, ... blah-blah
Now smart people know that ALL PARABOLIC RISES end in collapse, no parabolic rise in history has not been followed by collapse, its the nature of things, as parabolic rises are NOT NATURAL, they're always man-made engineered 'crowd hysteria',
Ok, so now the engineers of the parabolic rise, take their profits, cuz that's what smart people do, only IDIOTS, MORONS, and FOOLS "HODL".
The other thing that happened in Dec 2017 is that FUTURES went online, which meant whales could sell with covered insurance, they all had been waiting, but nobody could sell HUGE blocks, without effecting price, but futures were a way to cover the drop that followed, so you had massive selling by whales in 2017,
Following xmas the banks shut down credit cards, with already 50% drop in BTC many people who had bought btc 100% financed, were looking at not being able to pay their credit card debt, so they sold their btc, ... and then the ripple effect started,
In summary, the collapse meant nothing, what to look at was the criminals ( exchanges ) and ponzi promoters that pushed the 'HODL' narrative in 2017.
