The most rentable works in dofus touch

Miner and Lumberjack were good source of income before bots. I personally buy a lot of meat for my characters. So I'd say Hunter/Butcher since they are not that affected by bots and relatively easy to level (compared to crafting professions nowadays).

If you have more than 1 character, you can learn Hunter on all of them to drop more meat.

Good luck!
