If you never saw BNB hit above 450 then you missed out on its ATH, we peaked close to 700 dollars at the top. Also this isn't a question about what it did, it is about what it could do. Meaning, in a world where bitcoin is 100k, eth is 10k, then why not bnb at 1k? That is a possibility and it WILL happen one day. Will it happen soon?
I doubt that, I do not think that it will happen anytime soon, earliest I can assume would be 2023, probably more like early 2024 to be honest. That is why I am not going around telling people to buy bnb right now, or any other coin, do what you do. But, I know for a fact that when the time comes, everyone will be getting some anyway.
I was thinking about this as well, if bitcoin goes ATH again then the likes of BNB and other altcoins will do the same. But honestly, not all of them will follow BTC.
And for that to happen, the very likely year on my mind is just after the halving. So we saw bitcoin go ATH every after the halving and then next to the alts, so most likely 3rd or 4th quarter of 2024 up to its next year of 2025. Well, that's the thinking I've got if I'll base it on the scenario of the past.
