The word after will make it possible. 10-20 years later Bitcoin will reach more than just $400,000. And that is still after halving, right?
History is good to be used as reference but we need to be reminded that before, during the last halving of Bitcoin, the price is still low. Meaning, it could easily multiply some folds. But with a price as high as $8,000, it cannot easily multiply just like before.
