For ATH BTC, it will reach around $ 100k-$ 120k, it is very possible, however, we also have to match it with the current conditions and situation. The price is still $30,235. Will it be in early 2024 or in the middle of being able to, I will also be very interested in watching it.
Indeed. Its ATH can be $100k or $120k but we don't know when it is. It can be in 2025, in 2029, or in 2033. 
To predict the possible ATH to reach, it is surely depending the current situation. However, it is not something easy to analyze it. Even if we can count it with a certain approach, sudden news can ruin it. That's why people always said that the price is unpredictable.
I'd like to believe that the next bull-run all-time-high will be approx. at $141,340.00 - Pure prediction, I will start selling at $120k and above.
How you know it? I know it is a pure prediction, but you must have an approach to claim a certain number like $141,340. And I think $120k can be a too high for the minimum target to sell your Bitcoin. Who can guarantee that BTC can pass $100k? How if Bitcoin even can't achieve $69k again (its last ATH in 2021)?
