Do you have a way to earn passive income or are you just selling loot?
Get your hideout sorted, takes a while and costs a lot. You can make things based on loot found in raid. You can get a water collector which then combines with sugar to make moonshine, that sells for 300k a bottle.
Bitcoin farm alone will net you about 2 million rubles a day doing nothing else at the moment.
You can also make ammo, even the most basic will turn a profit.
Scav as much as you can, every time timer resets, do scav runs and learn the maps, treat is as a 'free' life.
Also as you upgrade hideout, Scav time decreases, at max level you can scav every 11 minutes I think.
