An ot question: do you feel really safe with a trezor? I mean, it isn't equal to a cold storage pc never connected to the internet, you connect your trezor via usb and if there is some zero day exploit your btc are gone, or there is something that can truly make more difficult for an attacker to dump the memory of your device?
Trezor has been designed to prevent exactly such situations AND it's great for a long-term storage.
Dumping memory is not possible, testers have tried.
So the answer to a question
Is Trezor more safe (or better) than an offline computer or a paper wallet? is
Definitely YESwhy?
+ the private keys have been generated offline (inside Trezor) and never leave the device
With Trezor you avoid the risk of uploading private keys to a potentially compromised computer or mobile phone, or a printer's internal storage.
+ malware cannot access the device via its limited USB protocol
+ you can use your coins anytime
+ you don't need to do any periodic backups, any further encryption and stuff that requires specific knowledge.
