The returns of Bitcoin bull cycle are diminishing with every halving.
From all these observations, we can speculate the average time period after which bitcoin enter into the bull cycle.

Total number of months taken after halving to enter into the bull cycle/number of halvings
(2+10+6)/3
=6 months
From the above calculation, we can safely say that bitcoin takes 6 months on average to enter into the bull cycle, and it is not surprising even if it takes more.
Now, to answer the question of when will the next bull cycle start, we can safely speculate that the next bull cycle can start within the next 5 months according to the analysis of the previous data done above.
