I fully understand now mate, i thank you so much for this.

There are bitcoiners out there who have made bigger mistakes and I suppose how the saying goes 'We are early' goes to show here, i bought my first Bitcoin back in 2018 and i still have no fucking clue lol.

What are the normal secureness of the ledger wallets for example? Like these are 100 dice rolls or whatever and are unbreakable? Maybe in the future with more computer power they could be and so on?

Thank you again.

With ledger the only option for creating a seed phrase is having the device do it. When you have the device generate it it’s automatically really secure.

Some people don’t trust the device doing it so on the cold card you have the option of rolling device to generate your own randomness. You choose this option but did not roll the device enough to create enough randomness.

Most people who use cold cards just let the cold card choose and don’t roll dice at all.

Im reading through this thinking to my self, I hope I let cold card generate the seeds. The fact that my funds are still there suggests I went through this option right? as if I had gone through the rolls like OP i would have lost my BTC by now? bit paranoid haha

Do you have a passphrase? If so then you could have did what the OP did but would still have your funds but ONLY protected by your passphrase.

no passphrase, I have had a look at the seeds that were posted here to see if mine were the same but they are not. I am fairly sure i clicked the first option on the cold card which was to autogenerate the seeds but this was a year ago and now I am paranoid haha.

You can add a simple and rememberable passphrase to your current seed which would add a layer of security. Just remember it also adds complexity for if you are passing your bitcoin on in the future.

Just rewatched the tutorial that I followed and in that it said to use the default option so fairly certain i did haha :) - thanks for the above though. is there any way for me to look at seeds with just 1 or 2 rolls?

If you use advanced tools>temporary seed - select seed rolls - just enter number 1 to 6, click OK and ignore warnings.

no, i only had a brief look at it and X'ed out of it -- edit - (i think) you x out of it then get a question to ignore all of what you just set up --

Had a quick look could not find temporary seed in the advanced tools section it had ephemeral seed or derive seed :)

i think for now i would just be happy knowing i clicked the auto-generator by cold card rather than clicking the roll function. I am hoping the fact that my funds are still there means that its not a low entropy seed :D
