Worth dumping my extra cash into Bitcoin at the ATH?

Hey Reddit, I've been DCA bitcoin for the last year and have held since 2018. I put a big chunk of my cash in BTC last month but just got another extra significant portion of cash that's sitting in a HYSA account. I'm all for BTC and think it's more valuable than the dollar but I feel a little silly buying a lot at the ATH.

My main thought is to just significantly increase my DCA daily amount.

Any crypto financial books/people/videos I should look into?

Thanks in advance strangers who benefit if I buy at the top!
