My estimate is that in the next 6 months there is still potential for ATH. but it cannot be predicted whether ATH will increase significantly or even decrease. depending on the market's response to crypto. so maybe we really can't do that analysis to see how crypto's potential is in the future
ATH can't decrease, when you reach ATH that is there forever until you break it and make it higher, there is no scenario where ATH becomes lower. However you probably mean maybe the price will drop or maybe the price will go up and we can't know that which I do understand however just because we do not see the price going higher or lower doesn't mean that we can't guess if ATH will be broken or not as well, why? Because you may think that it may go to 20k or 50k and that means you do not know price going up or down but you do know that the price will be lower than ATH, which is an example that you may know about ATH while not knowing about direction.
I personally believe exactly that, I think price may go up or down I do not know about that, but I am 99% sure that bitcoin will not break its ATH, that is just 2x and then some and it doesn't look like we will get there.
