Bitcoin Piggy Bank for Kids - Would You Buy This?

[ModuloMadBTC]

I'm a parent who owns Bitcoin and struggled to teach my kids about it in a tangible way. Everything is abstract - wallet addresses, keys, satoshis.

So I have a concept mockup for a physical Bitcoin piggy bank:

HOW IT WORKS:
- Parent loads NFC plastic tokens with small amounts of BTC ($5-10 in sats)
- Kid deposits physical token into the piggy bank
- Bank reads token via NFC, transfers Bitcoin to child's wallet in piggy bank
- Empty token is “pooped” out the bottom for reuse
- LCD screen displays balance in sats

TARGET:
- Ages 6-12
- Price: $60-70 retail
- Includes extra reusable tokens
- Parent app for management

QUESTIONS:
1. Would you buy this for your kids or as a gift?
2. Is $60-70 the right price point?
3. What security concerns would you have?
4. What features am I missing?

Just doing market research before investing in prototyping. Honest feedback appreciated!

The biggest security gotcha here is the NFC token framing. If those tokens are just IDs that trigger the app to send BTC, they're basically arcade coins, which is fine, but then the actual wallet lives in the piggy bank or parent phone and needs sane guardrails.

If the piggy bank is holding keys, I'd want it to be watch-only by default and have "spend" require a parent action on their phone, otherwise you've built a $70 gadget that can be griefed by anyone with a cheap NFC reader and 10 minutes alone with the kid's backpack.

Also please don't make the kid's wallet a single static address that you keep reusing, that's a privacy fail and a great way to teach the wrong lesson early.
