I think companies convert their cryptocurrency to fiat after ICO to avoid volatility, but not sure about that. Your Ad network will accept cryptocurrency and that will save money, but companies like google and fb they have Effective ad network, so what will make those companies choose you over them? beside payment mode.
Well actually dude, base on my own understanding crypto currency is very demand and popular in the cyberworld as well as in our society ehich can earn more profit even though its volatility it will still depend the demand of their product or advocacy in the society.
No doubt about that, but companies don't like keep all their money in cryptocurrency they prefer fiat, Company if its budget is in digital currency and price go down lots it will be a problem for them and they have a roadmap. Anyway this is not the main point, I was asking about what will make companies pick their service over others ad networks like google , fb.
