Their word list and checksum rules differs and if you try to enter a BIP39 seed into Electrum
it may consider it invalid and reject it
Again wrong. Electrum allow importing BIP39 seed phrases.
Maybe the user Ambatman never restored his wallets in Electrum software or he forgot about BIP39 option when importing.
Like I said manually. I meant it's not something that just works automatically without manually choosing it.
P. S used and still uses Electrum.
The words used by BIP 39 are quite different from that of electrum.
No, electrum and BIP39 use the same wordlist.
[/quote] I'm quite confused.
Then why the difference in words like the scenario OP faced.
I thought they had same number but quite different words.
