The only answer to give to newbies is to suggest to do their own researches. There is literature everywhere, we are not in 2010 anymore.

The only thing about this is, its almost impossible to cover every basis, unless you've written a very thorough guide. Since, there's plenty of things users could run into that could give them a problem, regardless of the wallet. Ideally, they'd be coming into Bitcoin with some sort of base line knowledge, but that isn't the reality, since most are eager to use it, which means they'll likely make mistakes.

Hell, I've made mistakes. Definitely, have learned from them, and luckily it didn't result in loss of coins. I basically came into Bitcoin to give it a try, and potentially earn some money on the side. I don't think I appreciated the actual capability of Bitcoin before using it. I learned that gradually over the first few months, and years.  

That's true, although its often broken up into multiple sources or doesn't cover every problem that someone could run into, it's usually the most common, which is decent enough. However, not exactly fail safe.

If I had a criticism of Bitcoin, would be lack of simplicity. However, I don't see a easy way around it, so it's a pretty weak criticism. I guess it's more of observation then. I actually believe it's one of the reasons we haven't achieved more adoption, than we have.

Bitcoin isn't easy, and to use Bitcoin safely you need to do research. You don't have to do that with cash. Over time, it has become to simple, and dumb downed, that they teach children at a young age about money now.

It is not because of the scheme, it is because the wallet has to be recoverable and if you create different address types from a single seed phrase the recovery process becomes more complicated since the wallet would have to generate all address types at different derivation paths which would also increase the time it takes to create the wallet for the first time.
But if you only create one type, the recovery is pretty easy.
The same challenge is present if the mnemonic type is BIP39.

The things is that lately Electrum kinda tries to convince its users to go for SegWit (bech32) addresses. Which is OK, since they can benefit of lower fees and LN too.

If you don't want to have multiple sets of seed words, you can generate a seed with a different tool and then import it into Electrum, just don't forget to check the Bip39 checkbox.
One tool at hand is IanColeman's, just you have to use it safely offline and you have to acknowledge that some consider the entropy of web-based apps not good enough for the best safety of the seed.

And without asking questions. I have pointed this out many times going back years:

Telling people to use this or that without asking or informing MAY help.
It MAY NOT help. We all have our "just do this" line. Even years after posting the above I still do it.

But asking a few quick questions will probably help a lot of new users have a better time of it.

Thank you for coming through, Pooya87. I've been trapped in ch05.asciidoc, struggling to finish the derivation path, but you helped me out.


I think this is where the problem lies and I have done more investigation on it. You can manually generate the derivation path in any way that you prefer but most often, each wallet has its default settings, however, the Electrum wallet does not produce BIP39 seed words due to the inherent version number. To verify this statement, I tried to create a new legacy wallet using the seed word I generated earlier, but it always detected it as segwit, and when I changed the option to BIP39 seed, the checksum was invalid, which proves the electrum seed phrase is not BIP39.


I blur some part of the seed phrase, it is for test

For further satisfaction, I used https://iancoleman.io/bip39/ to verify the same seed phrase, it says invalid Mnemonic, which means that it is the seed phrase generated from electrum wallet and not derivation path.

I played with the Iancoleman converter to flip between BIP44 and BIP84, and I discovered how versatile a seed phrase can be when creating segwit and legacy addresses. The cool thing is that when you produce a seed phrase with https://iancoleman.io/bip39/, it gives you a default derivation path for segwit as m/84'/0'/0'/0 and m/44'/0'/0'/0 for legacy, but the structures and addresses changes when I modify the values of each level.

I always assumed that if a beginner wants to learn something, then he must understand that this will require his brain and quick wits. Isn't it?

Having advised an Electrum wallet, it would probably be fair to find a guide and learn in-depth all its subtleties.

There are a lot of instructions on the forum regarding this wallet, which is, frankly, stupid to be in your situation.

It's time to understand that it is impossible to teach a person strictly according to the fads until that person himself begins to search additionally.

If you are given a new phone with a lot of features, will you only use it for calls, or will you still read the manual?

It also depends on the wallet.

If you use Electrum, then yes. You have to create a new legacy wallet.
If you have a Ledger hardware wallet and use Ledger Live, you can create new Bitcoin accounts for all 3 types of Bitcoin addresses. 4 if you consider Taproot as well. Be default, LL will create a native segwit account, but with a few clicks you can change it to legacy if needed. Why a legacy wallet would be needed in 2022 is a different story.
