Title: Receiving address reuse with trezor wallet
Post by: Franckback on November 24, 2019, 02:20:09 PM
Hello all,

Are my Bitcoin at risk if I used the same receiving address multiple time with the Trezor wallet ?

When I first start using Bitcoin I reused the same receiving  address several times, (maybe 15 times)  then I red that the right way was to create a new address every time, so that's what I did after.

I'm asking because I stored the backup seed in 2 different locations that  I'm happy with and it's not really that easy to access.

I won't keep that Bitcoin account for more than 2 years.

I'm wondering if it's worth the trouble to create a new account, transfer the funds, store the 2 new backup seed in different safe locations again ?

(I'm not really worried about privacy, just the safety of the funds.).

Thank you.

You don't have to worry about it then. There is no point in creating a new account and moving the funds there since address reuse only affects the privacy. In fact, without a proper coin control, it also doesn't matter if you use a separate address for each transaction. You will be able to recover your coins without any problems.

Agree on this. Besides that. Trezor is a hardware wallet meaning your coin is of the internet once you disconnect it to your computer. So your funds is safe even though you reuse your wallet address. Unless you delete your wallet address and forgot the recovery seed then that the risk will start.

Those are all small details which might confuse newbies.

Agree on this. Besides that. Trezor is a hardware wallet meaning your coin private keys is of the internet once you disconnect it to your computer.

They don't leave the hardware wallet anyway.

So your funds is safe even though you reuse your wallet address.

Address reuse is not related in any way to how hardware wallets work.

Unless you delete your wallet address and forgot the recovery seed then that the risk will start.

You can't delete a single address from your hardware wallet. I guess you meant wiping the device.

Although privacy doesn't concern you much, you can use electrum[1] [2] if you want more control over your addresses and hence privacy.
If you have some time, read more about reusing addresses[3] to make sure you are safe.

I learned there is no account for bitcoin. I think you mean your hardware wallet. Those word used for to mean receive or store bitcoin is 'Wallet', 'Address' and 'clients'.

I'm wondering if it's worth the trouble to create a new account, transfer the funds, store the 2 new backup seed in different safe locations again ?
Did you mean that you will buy new hardware wallet and move your fund there ? If yes, then you are free to do it but it doesn't mean your previous wallet was on risk just for revealed your bitcoin address. Your private keys stored into your device, your public key is a hash of private keys and your address is a hash of your public key. So hash is not reversible mathematically, means no one will able to find your private keys.

Since you are not worried about your privacy then there is nothing to worry about your fund. You are fully safe and reason has describe above.
