How do hardware wallets for cryptocurrencies work?

Question

Cryptocurrency

as everyone knows, there are devices in the form of USB flash drives for storing cryptocurrencies
and everything is stored offline
there, the question is: For example, I gave my friend the address of my wallet and told me 1BTC skin
and after 10 minutes I turned off the hardware wallet and put it in the safe
and after 20 minutes mine a friend will send me 1BTC from his wallet
and I forgot about my wallet and only a year later connected my wallet to the computer
what will happen in this case with the transaction that my friend transferred to me?

Answer 1

"what will happen in this case with the transaction that my friend transferred to me?" - the transaction will be recorded in the blockchain and will be stored there "forever". Your wallet only gets access to the blockchain, not the transaction. At best, it is just one of the network nodes.

Answer 2

the advantage of the wallet is the complication / impossibility to put the virus in
and the material feeling, and not "somewhere on a flash drive / screw"
is it worth 70 euros?...
