AFK Mining! is a great way to make money, u will make 25mill evry 10Hours (if u sell gemss for 50 Each)
Basing! i suggest to only use this ability if you have VIP Printer's or Special printer's, u can also combine this with Ability 3!
Growing Drug's By growing drug's u will make about 100k evry 10Minutes So if u want 1mill u will have to do it for 1Hour and 40Min if u combine this with Ability 2 u will make Good money
SHOP! u can always put stuff in your shop and sell it, even if u put Expensive item's Ex: Milkor 2mill Some ppl will buy it and the great way of this is buying stuff for the normal price and sell it by adding 250k evry time!
Iknow im not the only one who made shit like this So i hope i helped u guys alot.
