You are starting to sound a bit like Adam with his $32k in 1-2 years that he was repeating in 2015, 2016 and into 2017 - except you are a bit more specifically timing yours for 6 months after the halvening, and it is appearing that $50k plus would be a bit more conservative for late 2020 or early 2021 than $32k would have been while Adam was predicting $32k for 2017-ish (but his time line seemed to keep changing, too). 

To me, the odds of your steadfast prediction of $50k plus happening within the timeline that you state seem pretty decent, which justifies putting a decent amount of stake into BTC (especially for those who are currently no coiners). 

I feel that I have always had a sufficient amount of coins into BTC for such a bull run (probably since late 2014), even though I have continued to stack BTC since after late 2014.

Let's say, for example, that some no coiner has $100k in total quasi-liquid investments, and I include 401k value in that calculation.  1% would be $1k into BTC, but $10k seems to be a bit of a stronger stake.. put up to 10% without having to leverage. 

I did something like that in 2014 with what ended up being more than 10% of my total quasi-liquid value, so the bull run in 2017 caused my BTC investments to become more valuable than all of my other investments, including my 401k, and even with the large price drop of BTC, the value of my BTC still is larger than all of the other quasi-liquid investments that I have.

We know that history does not exactly repeat itself with any kind of exact similar performance, but having decent odds of another nearly 14x increase in value ($50,000 / $3,600 = 13.89) seems like a good investment with good odds. Do your own research and your milage may vary.
