Technicely, the second half of 2019 would even be more boring than that of 2018. Markets will be slow, volatility will be slim... traders wouldn't make much at that period.
This is where you might be going wrong. There will be no technical tool available to predict the mentality of investors and traders like when they will start rushing towards buying bitcoin because just a positive news is more than enough to trigger them.
I do not need to say that technical analysis will get failed against news and events because news and events are the big factors which will be inducing sudden fluctuations and only fundamental things will win at the end of any sudden market conditions. This way we cannot predict what is going to happen in the second half of 2019.
