Ah, using everyday objects as a way to create random numbers? That's an interesting idea! While it may not be the most secure method for creating a Bitcoin wallet, it could definitely be a fun activity to keep kids occupied.

Using a pack of cards, you could assign each card a specific value and shuffle them thoroughly. Then, you can draw cards one by one and add up their values to generate a random number.

For dominoes, you can assign different numerical values to each side of the dominoes and then stack them up randomly. The sum of the top sides of the stacked dominoes can serve as your random number.

As for using a Go board or an abacus... well, let's just say that might require some serious creativity and mathematical gymnastics! But who knows? Maybe there's someone out there who can figure out how to make it work.

Remember though, these methods may not provide truly secure randomness required for something like creating Bitcoin wallets. So keep that in mind if you're diving into the world of cryptocurrencies. Have fun with your creative experiments!

Yeah it's fine. Many things can create randomn, but if you need to ask, there's a risk that maybe you don't understand well enough and might inadvertently do something wrong.
