Video: A bitcoin allowance teaches spending and security

Kryptina is one of the world's youngest users of the digital currency bitcoin. Her dad gives her a bitcoin allowance as a lesson in online security and money management.

Like many other kids, Kryptina gets an allowance when she does her chores. But hers is not in cash. 

Instead, Kryptina – who at 9 became one of the youngest users of bitcoin in the world – gets her allowance in the increasingly popular digital currency. 

Kryptina's dad, who goes by his hacker name Tuxavant and is now a Las Vegas bitcoin consultant, started giving his now 15-year-old daughter the bitcoin allowance to teach his daughter about responsible spending. In bitcoin's earliest days, he says, "there weren’t very many places she could spend it, so she would need to cash it out with us and we would know how she was spending it." 

Today, bitcoin is much more prevalent. Tuxavant uses it to pay the bills for his office and landscaper, and Kryptina sets aside the electronic money for her summer camp and singing lessons. It's also much more valuable: When Kryptina first started using bitcoin, one was worth just six cents. Today, it’s worth $741. 

With bitcoin's value appreciating, the allowance has also become a valuable father-daughter lesson in digital security. If users don’t properly protect their private keys, digital thieves could steal them and spend their electronic money. So Kryptina uses encryption to protect her private keys and makes backups of her data.

Security Culture

This journalism empowers people to understand the bigger picture of cybersecurity as it connects to some of the most personal parts of their lives: their job, their education, the evolving digital culture around them, and the technology they use on a day-to-day basis. As part of the Monitor’s overarching commitment to chronicling human progress, we see these very human issues within cybersecurity to be critical and overlooked parts of the conversation.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to
