I pay wealth tax (Italian side) based︇ on what my accountant said i was worth.
I never corrected him, he never asked,︈ and that was the end of it, it's roughly 0.05% or something silly.
In the︉ grand scheme of things it's not much, Non-Resident, Non-Citizen.
Crypto is tax free︍ i believe in switzerland, will have to ask a friend but pretty sure that's the︎ case... again, in my position, the accountant told me i was worth x, i never️ argued or said anything different, there was a twinkle in his eye and it was a nice amount for the canton so everyone is happy.
Ergo - let your accountant deal with it...
