It was answered , 60k is the lowest and we still waits for the highest but so far the record shows 74k is the highest value of bitcoin before the halving.
Bitcoin does not go below the price of 60k$ so it is the lowest price before halving and now the price moves up to 63k$ so we hope the price will not go below this value so we can see good surges due to halving. I think 73k$ is the highest value of bitcoin and we do not examine another pump before halving that can bring more valuable price of Bitcoin so it is the maximum value before halving.
I assume that this halving will also be a better one like that of previously occurring halving but still the price does not elevate to the highest value so we have to wait because good news takes time to originate. Bitcoin once touched the value of 73k$ does not move again to such value so maybe due to halving this value becomes easy to achieve again.
