So before anyone is just like "not happening", allow me to explain

ahem a new currency not using actual money to get: rubys(the item could be changed to emerald or diamond, ect) Rubys would allow any player to get them, But they would be hard to get and can only be used for curtain plat items. They can also NOT be PURCHASED with ACTUAL MONEY, and only some items (new cool blocks or fun weapons) could be purchesed using them. rubys could also be turned into blocks and ruby ore could be randomly found (ruby ore is explained down further.
super hard-core dungeons or just harder that the spike trap ones would have, instead of gold rewards, gold to ruby trade systems, where you can only get 5 a week and they cost 1000 each ruby, allowing desperate players to get some plat items for their needs. though some items, like town blocks, would not be available with this new currency.
another idea using this form of currency is contests, were parkour races or pvp or TDM champions would win rubys. They could be hosted every month or so, and anyone can enter.
one last idea is treasure hunts, where on 3 days a month, you get a shovel, and "Special dirt" (gleaming/glowing/colored dirt) would be diggable, and it would be a rare 1/10 chance u get a Ruby ore (the "special dirt" would have around 10 blocks for every 100x100 chunk). Ruby ore can be turned into rubys with a smelter, wich costs 300 gold and pressing E next to it would grant 1 ruby for every click with said amount of ruby or in inventory.

please consider some sort of currency like this, because i spent over 30 min from 11:30 pm coming up with this shiz, and im proud of it, so at least grade me on how well i came up with it from 1-5
