What should i expect of the economy next league as a newer player?

Treat 0.4 economy as if it never happened.

The economy was about 10x inflated compared to previous leagues. I’m not saying to expect things to be 10x cheaper next league, but as long as they fix temple next league and don’t release a new broken moneymaker mechanic then definitely expect the value of divine orbs to raise and everything else will revolve around those prices.

Don’t expect it to be anything like this again. This was arguably the most loot filled season in PoE history

we don't know, they are doing a big revamp of the end game which means re balance of the existing map mechanics which at the same time means new economy.

Also if you made a lot of currency crafting that means you know how to craft good/decent items so you'll probably be fine. Meaning you will be making good money again.

I believe on poe.ninja you can view past seasons currency exchange rights. Might help to give you an idea.

The value of items will remain consistent, but the numeric value in divines/mirrors will drastically change. If you know how to craft you’ll be fine

After current league fun we can expect from next league running at 90+ lvls with some item slots empty.
