What are the best arguments AGAINST Bitcoin?

Disclaimer: I’m a DCA HODLer bullish on btc.

This place is an echo chamber of enthusiasts. I get it, I’m one too. But what are the best arguments against Bitcoin? And I mean against the underlying fundamentals, not the chance it may moon or may bust.

I am looking to challenge my belief in Bitcoin’s future in a healthy way, as we all should. This will either reinforce my commitment to btc or wreck it. Both are ok if valid.

Any Devil’s Advocates out there?
