A while ago silver got nerfed (I believe) because of a certain guy in Phillipines nation, since literally no one else has the same amount of time and (potentially duped) resources to dedicate as him, I think it would be nice if the silver chance could be rebuffed a bit to make it a viable income without being too easy, as right now the cost:profit ratio is uncomfortably close, as opposed to other money making methods (like mining and selling goods). Let alone the initial investment to actually have a good setup needed to make profit in good time.

Additionally, these setups consume a lot of power and can easily eat up a lot of time and money, fuels are expensive and lava farms are not viable for solo silver farmers, another reason why I believe reducing the nerf a bit will make this money making method less painfully profitable.
