What will happen after the MiCA law is fully implemented?

I was wondering what affect MiCA has on frontrunning and insider dealing etc.

They mentioned insider dealing, but what are they referring to precisely? Trancking the pending transactions and use that to your advantage? If so, that isn't insider dealing right? Because it is public, everyone can see it theoretically as long as you have internet.

I know MEV bots will be illegal after 2024, so can someone give me some more info? Or give me a link or something that can help me understand it better.
