We have seen this in 2013 in bitcoin. Please look at the bitcoin in 2013.
in 2013 bitcoin has seen over $1000 and dropped in December of 2013. (Bear year began)
in 2017 bitcoin has seen over 18,000 and dropped in December 2017 ( Bear year began)
in 2014 Bitcoin dropped more half of the price and never covered all-time high in 2014,
in 2018 Bitcoin dropped more than half of the price and still did not come back to where it was in 2018.
in 2015 Bitcoin has seen the lowest price until October 2016. ( Bitcoin has seen $200, A significant drop from $1045.)
in 2019 Bitcoin probably will see the lowest price until October 2017. ( $5000 )
In 2013, December Bitcoin has touched $1045 and went to $694 the same month but, in January 2014 bitcoin has seen $824.
in 2017 December Bitcoin has seen $18.000 and went to $14,000 the same month but, in January 2018 bitcoin has seen $17,000.
EXACTLY SAME THING HAPPENING RIGHT NOW!
according to my prediction bitcoin will keep losing value until October 2019. It is because according to history bitcoin always and always begins to rise in October and in November months and hits the all-time high in DECEMBER
Probably we will see, $5000 in March or in April 2019, and October or November of 2019 bitcoin will begin to rise. Please look at what happen bitcoin in 2013, 2014, and 2015, 2016.
All bull years begins in January of years and ends December months. The reason bitcoin failed this much is because the bitcoin investors know that bitcoin is coming to bear season ( "cashing out season")
There is no any effect about bitcoin news etc. in 2017, there were so many news about the bitcoin but bitcoin never ever effected from those news.
in 2020 a Bitcoin can be 100K or 250K. I don't know, but I know is Bitcoin moves with the percentage.
in 2013 from $13 bitcoin has risen almost 80 ($13x80= $1045) times that year and reached $1045.
in 2017 from $1000 bitcoin has risen almost 20 ($1000 x 20= $20000) times that year and reach $20,000
As a result, bitcoin will rise again, and once it rises it will be sky high.
How many people knew about bitcoin in 2013 and how many people know about bitcoin in 2017.
WE HAVE SEEN THIS MOVIE BEFORE IN 2013 AND IN 2016, BITCOIN WILL RISE AGAIN, BECAUSE of HISTORY ALWAYS REPEATS ITSELF.
It is still all a speculation though, but you did not place some facts in between where bitcoin actually made some few attempts upward before finally coming back to settle lower and then consolidated for a while before starting another uptrend entirely.
However, it is just the way things have been, and history always have a way of repeating itself, but in the end we have to understand that a lot of things have changed, development is happening pretty fast, and what we are expecting may not actually tend to become a reality, so all in all, it is all just an anticipated guess, based on past occurrences.
