To clear up a few things regarding DB. It is certainly not going to net you the gph that Immortal is currently due to their leaving game instantly. However, please keep in mind the Buddy team's history especially with HB, this bot will work its way up and very likely be the best on the market.
Ignore the idiots on their forums saying that it's difficult to make 180k/h, they are typically the stupid ones who have set it up incorrectly and then whine to the devs claiming it's the bot's fault.
DB is certainly not at the level of Immortal in terms of gph right now, but as far as safety goes I would trust it solely based on their history with making a joke of warden. In time I'm sure it'll be much better, and ignore the whining idiots who set it up wrong.
