Mainly Eff7 mining, and well... I sell plots in around several active towns, that helps a lot lol But before i did that I had a spawnshop, and sold features, and sold prebuilts/plots in my one little town
Frankly, I don't even know how I make money anymore. I just derp around and at the end of the day there's money in my balance. I've just reached the point where it isn't about the money, but the fun you have with friends.
I just got a town on Sunday and am trying to get all lacs removed. When I'm not doing that I'm mining.... With a regular diamond pick.
I make money by chance. If I get it, I get it. Do some donor services sometimes. Most of my time on ECC I spend building.
I mine and farm and sell items then store it in my forum bank where the stocks are so I get some extra cash
I make moneyz by selling apartments in my hotel and mining. Lotto aint my thing coz it gambling. DON'T GAMBLE my hobbys r fishing and selling fish and hosting 'Guess the amount of diamonds i will get when i mine!'.
Ive been pretty lucky and found plenty of abandoned mines. The rails are easy to collect and sell for quite a bit and so do spider webs. Ive also noticed that selling stacks of blocks i collect while mining whether its cobble or granite makes me quite a lot of money. So its mainly mining!
Mining, flipping high demand materials through my shop, building vaults...occasional melon farming and just being OP.
