Can someone explain to me why ETH has been surging recently?

Can someone explain to me why ETH has been surging recently? I'm worried it might crash down again.

I invested a lot of money into ETH in 2021. It hit its ATH that same year and I didn't take profit, felt pretty crappy about that. I've been pretty disappointed in the performance of ETH for the past year, but it looks like it's starting to surge again (it should be WAAAY higher, but alas.)

Is there pump and dump shenanigans going on? Should I take what profits I can get now? I wanna know why ETH is doing well all of a sudden because I'm a bit confused.
