BTC/USDT Cyclic Behavior Analysis

today's analysis of BTC is totally depended on its previous cyclic behavior,
previous top 20k to 3k bottom BTC took 52 weeks almost one year and it moves downward almost -85%
previous bottom 3k to top 70k BTC took 152 weeks almost 3 years and it moves upward almost +2000%
if we try to find out next bottom in the reflection of its previous behavior then expected bottom will be around 13k to 10k
and next top will be around 20000 and it will be in 2025.
its my own analysis I can be wrong so every one is most welcome to point out my mistakes
constructive criticism will be appreciated
