Yes, you will make some tiny profit if the price dumps back, but that's the best scenario.
Basically the LP providers are trading against the market, thus they are taking risks. But the profit they receive is not enough to cover the risks. So yes, I'm saying you cannot consistently make money from being an LP provider.
Also the wrapping fee is being paid by those who buy cheap from the pool and sell high externally or vice versa. So it is a fraction of their profit which is your loss
