How comes, like a week ago it was double the price.
Dump or ppl done with gaming?

Supply and demand. The more an item floods the trade market the cheaper it'll be.

It was going down to 95/100 before the patch,- then right after the patch the prices went up again to 120/125.

Now it's down to 70. Exchange rate for exalteds to divs in-game is crazy too, 148 per div.

Some streamers suggest that the economy will stabilize in 1-1½ months. While some people suggest GGG are going to release a new standard league in february or march. I find this highly unlikely considering how much more stuff they need to implement to stabilize the actual game before that can happen. But that's just my opinion.

I am personally guessing people are just dumping right now and the prices for divs might go up a bit if EA continues for several more months. At least that's what I hope

Market saturation + people finally realize how to properly farm quantity breach + delirium. Also console players got finally loot filter and maybe it sounds funny but it definitely had an affect on economy.
Also there is a limited divine/exalted sink in the game.

Agree, there is no new league coming within 2 months lol. Maybe around June at earliest. These price drops are totally fine and normal. Latest Poe 1 leagues prices tanked muuuuuch faster.

Lack of a divine sink due to limited crafting options.

Causes div to flood and prices up.

That is defintely a factor too.

i think div price tanked for way too long anyway, considering they confirmed economy reset recently it was obvious it will drop a lot, also duping bugs/1shot build for 10div dont help either

June is way too late. The devs said in their interview/Q&A that they intend to do new leqagues on a similar cadence to what POE 1 was like. Granted POE1 has had a break from major updates that has lasted a while but prior to that thye had new leagues every 3-4 months. That's what people are basing their guesses on. Based on that a window of late February to end of March... maybe early April at the latest seems reasonable.

It was mainly due to 3 days of duping mirrors

then why is ex price in game going up, last few days was 134 now 190 this morning
