Suggestion: add the bitcoin mining plugin from some other DarkRP servers! I think it will make an interesting way to make money, maybe even making a ‘Bitcoin Miner’ job
Steam workshop: not 100% sure, but you can find it somewhere, I will do some digging and post it here if I can.
Details: not 100% sure, maybe supremacy can add their own twist
Why you think it will be a good addition: there are only 3 good ways to make money IMO; Weed, Meth (kinda) and printers. I believe that this variety will spice up the server and add a new experience for players to enjoy.
