I think Powering up and partially delegating that Steem power in magicdice and tipu will be the best.
No to drug-wars because as I have observed the profitability in drug-wars is reducing gradually. Whereas gambling will be something that will keep on going and may increase as well.
If you have doubts why not diversify? Half in drug-wars and the rest in powering up and delegating it to magic dice. In this way you get MAGIC, STEEM POWER and also Passive income through DRUGWARS. In this way you will be minimising risk.
