This is one of the most ridiculous ideas I have ever heard of, especially with hosting an ICO for it.

In my country Shopping Centers give you free HotSpot Wi-fi, Telephone Boxes, even the local parks, so what makes paying for your service much better than what we already have when you want to grab the attention of investors, develop something that already exists which is free to the public & then charge for it ?

Go back to the drawing board
