One way is to buy stuff for friends and take cash from them. But this is also risky because sometimes friends u know 
One of my friends told me to convert steam money to cash is to give it away atleast at 20-30% discount. There are sites for this too but I never tried. find that risky
.
If you find a good way pls do share. I have some decent amount too 
DM me if you can offer games at some discount.
I too have steam amount. Let me know which game are you looking for and what discount you are expecting?
