Is the 4 year cycle dead?

Guys, don't you think if everyone knows about something, it's no longer an edge? Every random joe on telegram or discord is talking about the 4 year halving cycle. And how there will be an altseason and fireworks and best time to exit is 18 months post halving, etc. Now if everyone knows when to enter, when to exit. Who's gonna pump the price, and who will it get dumped on?

Secondly, there's people talking about how with etfs and institutional involvement, the cycle is disrupted now, and btc is operating more on a macro model now, rather than the 4 year cycles. What do you guys think?
