Looking at the chart doesn't always give an accurate price prediction. The chart always helps us make our own observations and decisions on where the price of Bitcoin might be in the coming months or years. But while making your calculation and prediction, don't forget the fact that bad news, which is one of the major issues behind the Bitcoin price's backward movement since last year, is not added to the chart, and such incidents always happen unexpectedly, which can delay the price movement of Bitcoin when it should have eventually met a new ATH high.

Due to some of those reasons, I always argue that the price of Bitcoin can't actually be predicted when it will hit a new ATH, halving or not. The price will still shake if we have some bad news, which will be strong enough to trigger panic selling.
