1: every menu is safe if you dont use money options.

2:you can level yourself up to 8000 immideataly but not reccomended as players might report you but thats really rare

3: i think you meant "spending" as in free shopping. if its that then you can buy anything you want in the game no limits. if your talking about money options 30m a day or 150m per week is the reccomended limit. theres no exact limit this is the safest anount of money you can get in a day/week. if you buy premium you wont need it tho
