I bought a few T5 Solo Maps and took them out to the black zone and to my suprise I earned well over 1M silver from just 3 maps.
This is something that new players could do even, with cheap, budget gear.
I'll be making another video averaging out a few hours of runs to see the profit/hour. I'll add all loot from chests in a montage and an excel sheet with sell price. I still think the average earnings per hour will be at least 1M if you can clear fast, because in coin bags alone I gained over 200K Silver. In Tomes 90k Silver Worth. That leaves just runes and your one or two good items, which is very possible.
