If I am in need of money I hit up the farms for a day or two. Usually I have enough money come to me without trying with nstars, voting rewards, sg, etc though.
I play the market usually with high-priced items like nether stars and exp, or I'll sell plots and apartments.
I mine and sell to the server. Ive tried to put one of my rooms up for rent, but, it didnt work out. My business went down the drain as well.
I also buy and sell xp and items, mine, farm, Pvp, and sg at times Sent from my iPhone using Tapatalk
It randomly appears in my balance from people who send me money. Other than that, I don't make money.
