I have been buying groceries through giftcards for over 3 years now and i have not died of hunger or dehydration. The cold is admittedly a bit harder. I dont have that one figured out yet.

But I am able to take my Monero and use it to interact with the brands and companies that everybody else uses.

What I was saying above is that for companies that accept different types of cryptocurrency directly, Monero is always in the top one or two spot.
