With the dollar plummeting, can someone explain why putting 85% of my money into a Swiss franc or euro ETF is risky?

I have been searching this subject for a few weeks and I’m looking for consensus. Is it a bad idea to put most of my money into FXF & FXE which tracks the euro and franc?

Buying in at record highs is not ideal but this could also just be the start of the dollar going downhill.

Pls lemme know honest thoughts!
