Cool idea of treasure hunting but why is it that they have to announce the player's location when it is about to get the treasure?  Now, thinking that with the system that selling lives in order to play the game, and millions of possible participants on this game, this is a good money grab option for the mod creator.  There will be sure a huge blood bath here fighting for that "treasure" thus, good sales for the lives requirement to play the game.

This also beats the idea of navigation, exploration and treasure hunting, instead, people will just wait for the notification that someone is near on the treasure and just pk that poor player.  Though, I know that there is some positive side on it though I only see developers raking huge profit on this one.

Unless the treasure is worth hunting and pk'ing, I will stay away from this kind of game system.

But, personal opinion aside, this is really cool since it will introduce crypto especially Bitcoin to millions of minecraft players.
