I posted this on reddit, but didn’t get any proper replies…
I just bought a Trezor safe 5 (BTC only firmware) for long term storage of BTC. I bought a keep metal aswell for securing my seed phrase.
I also want to hold ETH and ERC20 tokens such as usdt, and udsc.
So my question is, If I buy a 2nd device for ETH, can I use the same seed phrase as my BTC only device, or does that make the security of the BTC only firmware on my first device redundant?
I don’t really want to have to worry about 2 separate seed phrases, and they’ll be stored in the same place, so there’s no reduced physical theft risk by having 2 seed phrases.
Also, Im using separate passphrase wallets for each coin I plan to hold long term. I
So if I want to use just 1 seed phrase, and have multiple passphrase wallets, is there any benefit to having a separate device for my ETH tokens?
Is it only worth getting a 2nd device if I’m going to use a separate seedphrase for that?
Or am I better off changing the firmware on my BTC only device to multi-coin and just use the 1 device for everything?
Would really appreciate some advice on this!
