I think not investing in Drugwars has been a smart move. In spite of what they claim, it is a ponzi - payouts can only happen as long as people keep investing in the game. Once people stop investing, the payouts will dry up and no one will get his money back.
You got a Steem payment? You should tell me your secret, lol. I made the mistake to only buy Crack Houses so far, and drug production is really slow. From the investigation I did about the bots - of whom the devs claim they are not bots, but still... - I learned that all you need is 1 cocina to make some profit. But at this rate, I'll be happy if I can acquire a hydrophonic farm 4 days from now :0)
Yeah, my strategy has been not to upgrade training facility, upgrade hydrophonic farm, and storage so that you have 11k safe of all ( drugs, wepons and alcohol)
Now it is getting a bit difficult feor me as I require more resources than I have safe, so I get robbed. Will probabbly upgrade training f after all.
Or else I will have to uprade storage, but next upgrade brings safe down to 7.5k, maybe it goes up in next lv. do not have cocaina, but will go for a meth lab if I can get up to the resources I need :-)
