Dude posts on r/bitcoin that BTC "saved his life" because he couldn't access his bank account when he was getting gas and sold some BTC to buy some. I have some advice how you can save your life in an emergency like that.

Okay, the story is really tragic, so only read if you are emotionally prepared. OP was on a little road trip with his family and when he wanted to get gas his card didn't work. He called the bank and

they had froze my accounts due to "suspected fraudulent activity" and said there was nothing they could do for 24 hours

Sure, that's how it works, this is a real story. You know, it's just like that totally not just Hollywood trope but real thing that police have to wait 24 hours to look for a missing person. Okay, so in this real situation OPs life was threatened - stranded, probably in the US - how could one survive for 24 hours?

Well, fortunately OP found a solution:

I remembered I had some money in bitcoin. I was able to find a crypto atm (didn't even know those existed) within a quarter mile that I walked to. At this atm, I was able to sell some of my bitcoin and withdraw cash from the atm, which I was then able to use to buy gas to get home.

Phew, he escaped death this time. Someone posted this story on this sub as well before, titling it "That’s why we need Crypto". And that's absolutely true! But just in case you ever get into such a life-threatening situation and don't have crypto, I have some advice for you:

• don't die, ideally. There is nothing dangerous about the situation, worst case is you'll have to spend the night somewhere close-by and pay once your accounts get unfrozen (even though it's reeeeally unlikely that your accounts, plural, all get frozen and that your wife, who is accompanying you, seemingly doesn't have any)
• carry a bit of cash with you? I know, cash is not as obvious as crypto and many people don't know you can exchange it for goods, but it actually works quite well, with instant, free transactions

To sum up: don't make up incredibly stupid stories that try to show how useful crypto is, and then make up a situation that could much more easily be solved using cash. Yes, we all like crypto and hope it will have a lot of utility in the future, but we don't have to pretend it's more essential than it is in today's world.
