I'm not sure MNO's would like the fact that the ads they are paying for could end up recommending other cryptos if the user does not select the Privacy/Transaction Speed selection. Advertising by proxy is a bit of a issue, because MNO's are paying to advertise your app which then advertises dash. You might be able to get around it by having your app plug in the video be sponsored by dash as well, so the viewers see the dash logo.
It's not accurate to use the subscribers number as the Reach when say for Unbox Therapy only averages around 2 million views per video out of 9.7 million subscribers.
I do think that this is a valuable addition to our marketing. My main concern was other coins being recommended but I am satisfied with the answer that App Match provided.
This is a much better bang for our buck than alot of other advertising proposals, and instead of just having Dash plastered somewhere with no context this actively engages people.
