What are your thoughts on this? Personally, I keep all my BTC in a single hardware wallet. I’d like to know, from the Bitcointalk community: do you think the saying "don’t put all your eggs in one basket" also applies to those using a single hardware wallet?
I see no point getting two devices when one open source hardware device can do the job pretty well. A reputable hardware device is good but not as important as the seed phrase. Instead of him being cynical that a hacker can exploit a error in the code and steal the Bitcoin, perhaps let him channel same energy in guiding the seed phrase with his whole life.
