This Coin system works in a simple way. Firstly, a message in chat appears saying near what location the coin is spawned. It's not precise location, but says nearest location. After picking it up, you get +1 in database. You can make different rewards after reaching certain points and numbers... It can also be used as a event or something like that, just to make some more fun on the server. Here are some pictures: https://imgur.com/a/tvJ7tbW
