because if you're smart enough you would know that bitcoin bullrun is going to end this year and 2026 is going to start the bearish market or downward flow of bitcoin.
The future is unpredictable, there is no guarantee that history will always repeat itself exactly, nor is there any regulation that requires bitcoin to follow a single pattern (4 year cycle). Everything can break or change, and it all depends on micro and macro factors.
Just like in this cycle, Bitcoin hit a new ATH before the halving and that has never happened in the past. Likewise, historically it is not wrong to say that we will enter bear season next year, but can any of us guarantee that it will definitely happen? History can repeat itself or be broken at any time.
