Technical analysis makes a slight difference than solely relying on fundamentals and presumption based on current price movements. Though TA's focuses on past records and current movements of asset, but the chances for that specific analysis to happen is still 50/50 just like those who are just guessing the next price movements.
So, I have to agree the above comment, because no one would ever be certain on what would be the next Btc price.
We were once on the verge of lossing the $30,000 level, but It bounces back to almost $40,000 at this very moment. A lot of speculations say Btc is on its way on having the early correction.
I simply mean in the loosest term possible that "bitcoin can do anything it wants" because let's face it, in the technical sense it could be 1 dollars or 1 million dollars as well, that is even wider range than 20k to 50k range, however that is "technically possible" that we do not believe in, everybody knows bitcoin is not going to 1 dollar, and it will not be 1 million dollars anytime soon neither.
Long story short I mean that 20k is (or was at the time) only 50% or so drop away, and that is totally fine, it could definitely happen, however looking at 50k at today's price you may think that is easier, but at the time it was nearly identical. When the price was 35k, it required 15k drop to be 20k and 15k increase to be 50k, and looking at everything we have I felt like it was equal chances to hit those two numbers. Now looking at it, I could say 50k is a bit more possible.
