Glad to help where I can, but the one to chat with is @ecoinstant, he's a pro at dCity. He might even make you a good deal on a pre-made city! Ask him about that.

These days, the game is just about collecting tax credits, since every penny you earn will be snatched up by the current administration. Get some cards that produce SIM (wind turbines are cheapest), buy 'student' cards for 1300 SIM (0.38 SWAP.HIVE) and you will have a 1 SIM/day tax credit, which will earn you about 28% APR.

I actually think SIM tokens themselves are a better investment than dCity NFT's. Nice thing is with SIM is that you don't even have to stake it, just hold it. Your sim power is a 30 day average, so as you collect (or invest in) more SIM, eventually your sim power will get beyond 8K you'll start getting daily hive dividends! IF you get to one million SIM power, you can join the simillionaires club with it's perks!
