I had no idea that you can find gift coupon for everything on Betrifill. I saw they are even selling coupons for Hindustan Petroleum. I am not sure whether you can use them to purchase petrol or disel or gas. At the moment it is out of stock.
The only thing now left is to find a prepaid debit card that can be refilled using crypto and can be used in India.
Mostly you will find gift cards from Amazon or Flipkart and some other renowned brands. These are very handy if you are planning to purchase certain things that are available on those websites. You can do mobile recharge as well. Go ahead and recharge for the entire year.
Now I feel stupid for doing this day before yesterday when the bitcoin price was around 20k. Today the price has gone up and I could have spent less amount of bitcoin.
