I'm kinda agree with this mining problem
Yeah really it hardly get profit from it
I know there other job you can do but what if there a player that only like mining?
Well since it was peaceful (some may think it boring) and there no crab and player that keep killing you when you earning some money
Maybe mineral that we get from mining should be increased in some price or make the 10 level cap higher and make the requirement for each level up more less

Don't hate me if there something in my post it was just my opinion
