I may not agree to what you have said mate, Ethan and Scott have more ways if maintaining the site by hiring good and intelligent workers across every problems, a competent and due diligent developer will be handling yolodice while ethan and Scott go to bed to sleep while the site is running smoothly, to me the reason they stop operating is because, so many competitive cryptocurrency gambling platforms are emerging rapidly in the space with new gambling features far more better than yolo interface, there affecting customers from patronising them, on that note, yolo have to shutdown and maybe will sit back and rethink new features and strategies to come out with.
That is not what this is about, making money or not I can't say how much Ethan and Scott has, maybe they have a lot maybe they don't, but finding even 100+ staff is not the deal here. I think they have mentioned previously that we are talking about a huge number of new people coming in but also the bitcoin price is going up as well, which means they are making more money than they used to but still stopped.
The reason is the fact that the money they have right now became too valuable, and they just didn't want to get that type of problem in their hands, after all we are talking about god knows how many millions of dollars that they are holding on behalf of gamblers, it is not theirs neither, it is customer's money and they are taking the full responsibility for it. I think they just decided not to handle any more of that, who needs that extra pressure in life.
