Hello, I am a Russian person, I write through a translator, so I do not know how clear and correctly written it will be.
Earning Dynamite: Remove the creeper spawner from the shop , make another world-End, a closed world, just do for example 500x500 and everything else is an abyss, place the creeper spawner in this world and let the players go to this world and mine dynamos there, also make a portal that will teleport the player to spawn or somewhere else.
Earning money:Make sure that the basis of the farm on the server was a watermelon farm, that is, not a spawner, etc., but watermelons.Players will build a watermelon farm like a cane farm, but they will get a lot of money for it, just lower the profit of money from mobs and make it possible to get a decent amount of money for watermelons.
