BTC ATH (2017) & 2021 Altcoins Opportunities

Hey traders,
let us analyze the past after BTC hits ATH on 2017:
- LTC made its ATH same time with BTC , currently is toping as well with BTC
- ETH ATH took 28 days later even when BTC was dipping!
- XRP ATH took 21 days later

So could major altcoins make a new ATH after BTC is done ?
