My conclusion is that the bear market will end between May and October at a bottom price of $2800-$3000.
Compared with the bear market in 2015 there are many similarities. An import similarity is that the bear market started 9 months before the halvening event in 2016. At current time this would be translated to August 2019. This would be a price of bitcoin just below $3000.
However, some analysts such as Tone Vays and Tyler Jenkins predicted the bitcon price would fall to a $1000-$1500 range. Tyler for example used a different method to analyse and he used hyperwave.
A good strategy would be to apply DCA in combination of price levels. If you have a bag of 10k available to invest in bitcoin this year I would invest it as follow, starting from 1st of April:
Every first of the month - invest $500 (apr-dec = $4500)
In combination with:
At a price level of $3000 - invest $1500
At a price level of $2500 - invest $1000
At a price level of $2000 - invest $1000
At a price level of $1500 - invest $1000
At a price level of $1000 - invest $1000
And for the rest, just HODL! ;)
