I personly cant stand farming. The majority of my money comes from playing sg. The money I make isnt great but im fairly satisfied with my current balance so im pretty lazy and find most money making ways to be incredibly boring. Saying that I occasionally mine, I built up most of my balance by doing so. Im too lazy to do this now even though I do have an efficiency 7 pickaxe.
i find gaps in the markets. for example, some spawn shops sell diamond ore <75 and others buy 80> or quite often this is the same with auctions or trades. sometime it is quite time consuming, but it is very rewarding. i dont usually make a lot of money. its taken me about 7 months to get to mayor, then i decided to give an idea i had a go, and made 20k+ in a day ...im buying dirt with that money
Other, i got money for res buy winning a pump axe then i sold townds to get to pres then i stopped making money....
Ah, I'm kind of ashamed of admitting that nearly all my money has come from lotto haha I make quite a bit with my spawn shop (station 75, just throwing that out there... Just in case hahaha) but I've won 1 crazy lotto final round, like 5 crazy lottos and around... 6? maybe 8? regular lottos (the most I made with regular lotto was 170k and the least 6800) I did farm a lot when I was builder though. And a little more when I was resident. I must add that half of the items being sold at my spawn shop are gathered by me (the other by my partner) so I do a little bit of everything =D
Mining for money and then... 'investing' it in lotto. Actually works pretty well though, made over 700k this way.
