A tech reporter once lived on bitcoins for a week straight to test how valuable they were in the real world.
She bought a bunch of bitcoins in 2013 for $136 each on Coinbase, hoping to use them for daily expenses.
On the last night of her experiment, she spent 10 bitcoins on a sushi dinner for dozens of strangers. Today those would be worth about $230,000.
The restaurant's owner has now retired from the food business, thanks in part to his cryptocurrency earnings of 41 bitcoins, or $902,000 today.
