This kind of ideas attract attention and seem innovative, but when it comes to the truth, there are too many doubts around them. For example, how do you know that someone is dancing and is not walking on the street? Or, How do you know I have not put the sensor on my dog?
thats why i wrote that i would introduce this in my dancing club if i had one. you would have to be inside the club to be able to mine. you would receive a special gadget at the bar and without that mining would not be possible. sure, you could just walk around or something like that.
