Sig campaigns are good, but since primedice is done adding lower ranks you would take almost half a year to reach a point where you could join primedice again. If you can program you can make a lot as well.
Yes I know it would make things faster especially in the crypto world but unfortunately I don't have any of those type of skills.
As a full member, you can join Cryptcominer, which should give you something like $1.5 a day. It's not much, but it should help a little ($45 a month). You can also try selling stuff you don't need in the Market section. Even game accounts you don't use anymore might sell.
I wrote in my message that I actually don't own anything except my PC which is worth around 50$... Not to mention that it's almost impossible to sell thing from Serbia to the countries around or anywhere else.
They are really not too old and since they raised me from when I was five and my father died I really feel I owe it to them in a way. Hope you guys understand that.
I really need a fast solution for my problem since they are waiting for that surgery for over a month and their situation is critical. If you can help or have any ideas you can PM me and I will respond with more detailed info alongside with some proof!
