Bitcoin's price is volatile, so it is always unpredictable in the market.
I have my own pattern, but i'm not sure about this and i'm observing it. Maybe in 2021, it surpass an another ATH again because as you can see in 2016 halving and the ATH occurs in the end of 2017. Probably it can happen again at the end of 2021 which is not that impossible to happen.
We have different predictions, right now we are experiencing sudden increase in its price but that's not that good enough to say that btc will reach another ATH this year.
I'd like to believe that the market has matured and we are in a very different scenario now compared to the past halving, I don't think we are going to need 12 months at the most to reach another all-time high, after ten years Bitcoin has proven it's worth that many institutions have seen it's potential compared in the past when investors are just observing how Bitcoin will evolve in the hardest time and it did surpass their expectation.
