What do you think about the price in 2023? Can we expand it goes to new ATH at 90000 - 100000?
The new ATH, in my opinion, should be expected no earlier than 2024-2025.
Could you please also explain in more details about this 4-year cycle?
This is the cycle of bitcoin, expressed in annual candles, divided into phases of fall-recovery-accumulation-growth. These cycles change every 4 years.
When exactly the renaissance begins - straight after 85% loss?
I cannot say that we should lose 85% of the value of bitcoin anyway, but we can do it. I do not rule out that in this cycle the figure may be slightly higher, for example, 78% loss of value. Usually, after bitcoin loses a significant portion of its value, a slow process of recovery and consolidation begins, and this is when the renaissance begins.
And how does it correlate with the fact that most BTC price in the end of prety every year is higher that in the beggining? For example in the beginning of 2019 it was $3700, of 2020 - $7200, of 2021 - $31500, of 2022 - $46300?
If you add 2018, then your chain breaks, simply because 2019, 2020 and 2021 were in the same 4-year cycle (bypassing the fall cycle). Now, when the next fall has formed, this chain may not have a logical continuation. She might break again.
