Thermos is kind of hardware wallet is what I see theymos disclosed in his KYC image.
The Thermos hardware wallet has water-resistant charateristic, which is much better than waterlogs.
But, I still wonder how deep the Thermos wallet can be able to works fine before destroyed or damaged by water pressure?
It is enclosed in a water resistant steel housing and has been reported to work when sending bitcoins while free diving on the coasts of Spain.
Time to get serious now so I will stop with the jokes.
