Exactly @blakemiles84 - for people willing to pay for it, imagine:

It could be used for advertising - Say I run a store, and placed some steem-dollars around my store every hour - everybody playing the game would idle around there waiting for the next batch - which would again create a stream of new customers to my store since I could accept steemdollars for products, foods and beverages, and groups of people attract more groups of people, so even if I ran a hot-dog stand, I am pretty sure I could increase my business by dropping some dollars around my stand-spot ;)

It could be used to reduce crime - I could place steemdollars around the city-block at intervals, making sure there is always people walking in the streets 24/7 with cameras - criminals would have to stay away, too many witnesses - could even make a special version for guards, in order to collect their payment they would be instructed to go from place to place within minutes to check all kinds of corners and bushes - steemdollars delivered from @fyrstikken to @username if @username picks it up between 20:30 and 20:32 for example - would keep the night watchers actually moving instead of sitting in their cars sleeping on duty...

There is a lot of things to this in the idea-face, so please contribute with what you can imagine a system like this being useful for and what it can be fun for.

It would change the world out there for sure
