Hi guys, I'm still active on forums even though I've been promoted to helper! My idea with Mob coins is similar to cow coins (my casino stocks), except with mob coins you can buy crate keys and other good stuff like mob spawners. Mob coins can be achieved by killing mobs, the higher the tier, the higher the chances of getting them. That means iron golems could drop one mob coin with a 5% chance and zombie spawners can drop with a 0.5% chance. This isn't really 'my' idea, I just know there are plug-ins for this and really enjoy the trading concept of it. Chest shops could be made more popular by offering to buy mob coins. Overall mob coins would introduce players to the trading aspect of the stock market, as well as popularize the use of more spawners and more keys.
