Oh, just an idea to store backups of wallets or private keys or anything.
Pictures are worth a thousand bitcoins.
Put them all in a box or clear plastic bag, keep on your person, and you can go through any airport anywhere in the world. Unless you encounter a government that doesn't like kid's toys; don't go to North Korea maybe.
What a brilliant idea, even to keep as a secret location in the house.
it could be left in a pile anywhere.
The only thing is Lego is very popular at the moment, mind it isnt sold
on ebay by mistake
it is for sure hard to beat a memory wallet and can also be hard to remember the seed words.
What about a line from a favorite song or even a complete verse?
I have this nice little decorative keyring thingy which doesnt look like a USB
its only 4gb but handy for essentials
and the lid is very secure.
