In a couple of hours I will be able to start all the dCITY events again. I will not activate the Science Convention event because it's too expensive for me. On the other hand, with this event you have a chance to not only receive scientist cards, but also a STEM miner - each one is worth at least 20 HIVE!
So every 2 hours I will be able to receive cards such as gambler, addicted gambler, artist and I will also have a one time 20% chance to get a worker or a hard worker.
Normally each of these cards would add 1 point to the population, but because popularity in dCITY increases a population modifier, 1 point to population can actually mean for example 5 points or more added to the city.
Using these events is in my opinion one of the best methods how to stay in the leaderboards forever and always receive some HIVE from dCITY's reward pool. Unfortunately, the events can be activated only once every 4 days so somehow I still have to increase my population even when the events are not activated.
I already have 30% probability to bring new citizens into my city so then the last thing I can do is to check auctioned cards. I was for example very lucky to receive another ProGamer card from the auction for less than 60 Battle tokens! Normally dCITY players offer like 400 Battle tokens or more because it's another card that can help to increase the population and thus it's a really valuable card.
Stay sharp!
