beside that, $ 100 is too low for BNB if altseason happens, we all know that altcoin will be crazy. it is possibily to hit more
so, that's why he means that if waiting $ 100 for 10 years is the worst case IMO.
We might hit that price but altcoins are not BTC where the demand is for everyone.
BNB might already have their own change but it's not as successful as BTC's blockchain, still their exchange is what makes them valuable but we don't know what would happen in the future, hacking is possible again and they might be hit again, so we should also consider that risk.
