So that means my ledger wallet bitcoin wallet is safe right as long as my 24 word key and pin number is not shown to others? I want to make sure of this before i transfer the rest of my btc from electrum to the nano ledger s.
The 24 word seed phrase can be used to derive all of your private keys (and therefore to access all of your funds).
The pin is just a security feature against physical access to your nano (it will wipe itself after 3 failed attempts).
Hey all just noticed a strange issue. I was watching a youtube video where it mentions some man in the middle attack etc. They say when you give your btc address for someone to send you, you cant trust the btc address shown in the bitcoin address. First off, isn't that the address you are sending btc to from? For example when i send btc to nano ledger s, that is the address i copy and paste right? Because i did a few transfers and it does show up in my wallet.
Your transfers showed up because
noone was trying to steal your funds at that moment.
A man-in-the-middle attack doesn't happen 'by accident'. Someone has to be actively targeting you.
You can read more about a MITM here:
https://en.wikipedia.org/wiki/Man-in-the-middle_attackHowever according to the video, you are suppose to click on a monitor that would actually display the btc address on the nano ledger s. First off, there isn't that option. There is only 2 icons to choose from... one is to email and the other is to print etc. On the video, there is a 3rd icon you could click on etc which according to the person in the video, you could view your btc receiving address on your nano ledger s to confirm. Is there a reason why this doesn't show up in my nano ledger?
You should be able to see this button:
If not: What versions are you using (BTC app on your nano s / BTC chrome app / nano s firmware) ?
When did you update your nano s the last time?
The other thing is when i clicked on receive btc. why is my btc receiving address different from the ones i previously sent to? It still starts off with the number 3 but the rest of the letters/numbers are different. This doesn't make sense because shouldn't i only have one btc address since i did not generate another btc address in nano ledger s? I just want to make sure of this as i already transferred some btc to the nano ledger s already.
A new receiving address will be generated each time you receive btc's.
This is done for privacy reasons (e.g. to make it harder to see your overall funds).
You can still send coins to your previously used addresses. They will always be accessable and usable!
So that means i do not need to try to send any btc from the nano ledger s to say electrum just to test that it works right? Thus since i received btc to my nano ledger s without issue, then sending will be zero issues?
You can try it out.. but don't really have to.
If (most unprobable, but if somehow) the sending of your coins doesn't work you will still be able to import your 24-word seed into any other BIP39-compatible wallet (e.g. electrum) to access your funds.
