Yeah, it is 0.00175 * 1,000,000,000 or 1.75 million.
Assuming the vids were monetized. Which, "maybe," the VeVo. Which definitely went, "straight to the label." and Aviccii would have made about 98% of his money on tours. Unless he had a great financial planner... which, pffft, as drunk as he looked would have been, "unlikely," to say the least.
I'm sure his net worth was, "sliced and diced," by Swedish Taxes. And he probably was left with 50% at best of what he earned. Possibly 40% or even 30% Swedish taxes are no joke. Aviccii could have very easily grossed $100 million in earnings and been worth close to $25 million at his death
