I would say at the moment, at current fiat levels, I am comfortable with having all my savings (which are btc), on my hardware wallet but in the past, the idea of having even a few thousand on a hardware wallet would have seemed unfathomable (coming from a UK bank perspective vs like a Russian bank that i wouldn't trust for shit).
IMO, having it on a cex would be far scarier with their random questions and interrogations.
I often wonder if stackers of physical gold ever feel like shitting themselves when they have a ton stashed away in their basement.
My question to you stackers is, did it take you a while to adjust to having a fat stack (or even a modest one) completely under your own control? Or did you take to it like a duck to water?
