What will happen after the merge?

Hi Crypto fellas, I am pretty new in the neighbourhood and I have a question about what will happen after this ETH merge. I trying to understand the technology behind it, but honestly I am too dumb for it. And my curiosity is more about the repercussions on the price.

I know that nobody knows a shit about fuck and the 8 balls don’t work properly, but what do you think will be the most realistic scenario after the Sept 15th?

One of my bigger bag is of course ETH and I am just trying to understand what is the most wise move to do with it.
