Describe the solution you'd like
Mystery crate Spawns. there is a small percent chance that a "crate" will spawn somewhere in the mine. It would be a sponge or a chest or something, that it gives you a configurable amount of money or some other perk

Additional context
check out OP prisons on Lemoncloud or op blocks prisons. There are sponges that give you eTokens which u can use to rank up your tools or get money. Dm on discord to discuss.
