Not sure where you're from but in the United States you can recycle bottles/cans and bring them to a recycling area near you and redeem them for $0.05 each (or 0.05 cubits ea if you wanna think of it that way). Collect 20 bottles and that's $1.00 USD or 1 Cubit. Many other countries have similar systems for recycling where they pay you about $0.05 per bottle/can. Collect the bottles/cans at your house, find them on the side of the street, clean up after a party that has beverages, you'll find em.
Get a parent or yourself to convert that money into PayPal and there ya go!
Yes it takes work but that's just how the world works
