We have limited the amount of re-mines because after the data has already been provided, the value of the new data for the same location depreciates because it has already been provided.
While earning XYO in the COIN App, you may come across an error message telling you that you have "exceeded the maximum number of re-mines per hour".
Here's an example:
A store owner currently provides data to the network by geomining within the store. As a customer walks into the store while geomining, the data has already been provided for this location from the store owner, so the location data provided by the customer becomes less valuable.
In another case, if a store owner wanted people to visit their store, the owner may put big geomines around their store because they perceive the value of the locations near their store as much more valuable. They may put more geodrops down in order to incentivize geominers to visit that location, and potentially even visit their store!
