Just kidding. Of course, this is speculation. So I speculate that astronomical ATH means that we will all see another 10x of current halving price, (1st halving = 100x, 2nd = 30x, according to your numbers, so let's be generous and make this the last halving to see double-digit multiples).
With the price as of halving jogging around $8k to 8.6k, 10x gives a price prediction of within the price range of $80,000 to $90,000, it makes sense now. I'm beginning to understand why the prediction of bitcoin getting to $100,000 is been predicted all over the media, by the big names in the game. For bitcoin to record that massive increase in price though, I'm quite sure it won't be a one way movement like that of 2017 that just spiked all the way up to approximately $20,000 and immediately started retracing backwards.
The market will need a steady and healthy growth to maintain bitcoin trading for a long time at that level. It'll be disappointing if another 2017 all time high scenario repeat itself where bitcoin just touched a certain price and never did trade for sometime on that price.
