Are you living in India? If yes, you can have some gold for free.
Please install Freecharge, Phonepe and Paytm Apps in your smartphone. (You can signup with Freecharge and Paytm through a computer, but Phonepe needs their App to be installed).
Now find some relatives/neighbours/friends who wants to recharge their Phone/DTH. Be ready with the promo codes from Paytm, Freecharge etc and apply it while making the payment. For eg: Paytm offers a coupon MONTHLY20 for a recharge and you will get cashback of Rs.20 within a few minutes. Use that cashback and instantly buy Gold from Paytm App. Literally you are getting that gold for free.
Freecharge also provides such coupons. You can link the Freecharge account with Phonepe (inside Phonepe app) and use the cashback earned from Freecharge to buy Gold from Phonepe. Phonepe offers Rs.30 cashback for a Jio prepaid recharge. Don’t forget to buy gold whenever you get a cashback.
Try to make more ‘customers’ for DTH and mobile Recharge. For every DTH recharge, you can take a service charge of Rs.10 and add that money to paytm wallet through some friends. You can buy gold starting from Re.1 at Paytm as well as Phonepe. No need to spend any amount from your pocket.
No money to start recharge business? Go and signup at epaylater(dot)in and later at niki(dot)ai. You can recharge any mobile/DTH and choose epaylater payment option. You will get 14 days time to pay back. Just keep your Rs.10 service charge and pay the dues on time. Sometimes, Lazypay also offers cashback and try that too as a payment option in Niki App.
There could be some other Apps that offers cashback for recharges. But I am only using Paytm and Phonepe to buy gold for free. At present, I have 219.70mg (worth Rs.683.74) Gold in my paytm gold locker and 0.1702gm (worth Rs.510.26) in my Phonepe App purely bought with free amount.
Note-Iam not related with any App/Website referred in this answer. I am just showing a way to accumulate gold for free.
