Hello, I'm planning to buy a hardware wallet for myself.
I wonder if you need to synchronize your wallet from time to time in order to make sure your cryptocurrencies are not lost or something?
Another thing is - can those wallets break down over time so you won't be able to run them? What then, have you lost all of your cryptos there? Or what if you simply lose your hardware wallet, is there any remotely based recovery option?
Can any kind of malware steal your funds or private key or anything at all?

And what is the best hardware wallet in your opinion and why (compare it to others if you can)?
