The truth is no one can guess if Bitcoin will rich ATH one day or not. All predictions are probably bad shots, but it doesn't make a sense.
I do believe price predictions are silly but sometime make a sense. It does not matter if you are in for the long run. This is a long game for me, so overall we're good.
How long until the next ATH? may not much soon as there too much manipulation.
We may not be able to predict when it will reach ATH will it be this year or in coming years is unknown. But in long term it will break those records too and we have seen how it has moved from 10k to 12k itself shows that bounce back in bitcoin is very much possible and it will continue to happen.
