I like to travel with a hidden USB memory into a voodoo relic like this.
Nobody dare to touch it :)
Much better to travel with a stupid USB than a coldcard hanging from your neck...
One copy of the USB stays hidden in the dark, one to travel, one to your mother, just in case...
good tip.
I already have a lot of USB wallet, time to test than upgrade.
but in a situation where I have nothing with me I will could get my info online.
