Banks and any other regulated institutions will keep spreading FUDs for Bitcoin regardless, mostly by only random speculation like the bubble will burst as you mentioned. They know they do not have the full control of Bitcoin, so the best they could do is to just spread FUDs for sure. This counts for Musk as well, now that he dug himself a deeper hole from what happened.

At this point, there is not much to do but to test yourself to be a strong hodler.
