I think that merely exponential growth is disappointing to the devotees of the super-exponential curve fit.

When you are disappointed in the performance of BTC/fiat, it means that you are shocked and saddened at how foolish and short-sighted are the other members of your species.

The correct action then, is not to short BTC (which continues its inexorable exponential rise) but to short mankind, which apparently peaked around 1969.
