I honestly don’t know who will do that? If bitcoin was run by one individual then I could see this happening, but it’s decentralized so who is going to advertise it? And, how it is going to benefit any individual? So, it clearly is not happening UNLESS government gets involved. But yes, I think this might be solid option for upcoming ICOs because they could gain attention. Right now, I have invested in Upfiring, so advertisement as such for them will be great not for something like Bitcoin or even Ethereum.
