Gold Bloon’s extra gold gained per hit can discourage an opponent from feeding Gold to the player. It's a decent option for Aggro, forcing the opponent to hit it and make it either cheaper for free, or have it leak to deal a solid amount of damage.
Players with bigger collections may abandon Golden Bloon in Aggro due to better options being available. Despite that, for budget strategies, Golden Bloon can work in Aggro.
The Golden Bloon itself is a weak threat, equal to a +10 Health Blue Bloon that costs 1 Gold more, or a Swarm Green Bloon with 2 delay and 5 less Health. The benefit of it comes from attacking it at least once, where it becomes stronger than a Blue Bloon for the same cost.
Mortars have no control over attacking a Bloon at the end of a turn. If only Golden Bloons are on screen, you can force the opponent to give you more Gold. Defenders that have not spent ammo on other Bloons are also affected, but easier to avoid.
Against Quincy, his Perceptive Shot passive will activate the On Damaged effect. When played this way, it essentially costs 1 Gold plus the same amount of Bloontonium.
Try to pop or get Golden Bloons weak while hitting it as few times as possible. Bomb Shooter and Sniper Monkey are good counters to Golden Bloon.
