Title: sweep button greyed out in electrum
Post by: legend018 on November 26, 2017, 01:07:02 AM
I would like to sweep bitcoin from mycelium to electrum.
I put in my 12 word private key. Can't find information if I'm suppose to put it with spaces in a row or one at a time in a line.
examples: word1 word2 word 3
or
word1
word2
word3

anyways, sweep button never lights up. I tried looking around, not having any luck. Saw something about how it used to not support that kind of private key but that later versions should.

AFAIK it can only sweep private keys, not whole seeds. I'm not sure if there is an easy way to get your private keys from your seed.

I was able to figure out my extended private key, but when trying to sweep it into electrum it is still greyed out.

You are misunderstanding this I think.
I'll break it down a bit for you:
Your private keys are large numbers that hold your bitcoins.
Your Seeds are massive numberst that can be used to generate your private keys using algorithms.

What you want to do is follow this:
1. Click "File" at the top
2. Click "New/Restore"
3. Enter a name for your new wallet (this can be anything) and continue.
4. Paste in your seed words (as if they were a sentence - but without any puntucation). Select options and tick Bip39. Then hti OK and Next.
5. Put in the derivation path (I think it's m/0'/0, m/44'/0'/0' or m/44'/0'/0'/0 but I might be wrong).
6. Then you have your coins avaliabe in your wallet (if not, the derivation path is probably wrong).

I was able to figure out my extended private key, but when trying to sweep it into electrum it is still greyed out.

It won't take a master private key either I don't think.

I may give that a try if I can't figure out how to sweep.  I'm surprised there isn't specific instructions on electrum on what kind of private key their expecting, unless I am dong it correctly and it's something else. I'm using Ubuntu and I noticed the QR scanner isn't working.
Anyway - I thought I heard sweeping was best as it will sweep it away from the other wallet completely.

Sweeping is just the same as "sending"... you cannot sweep a seed, nor can you sweep a master private key... you can only sweep individual private keys.

So, first up, create a new Electrum wallet -> "standard" wallet -> Create new seed -> WRITE THE SEED DOWN!

Now, you're ready to get all your coins from Mycelium to Electrum... you have two options:

1. Open Mycelium, send all your coins to an address from your new "seeded" Electrum wallet

or

2. As jackg said, Create a new wallet -> call it "restoredMyceliumWallet" -> "standard" wallet -> I already have a seed -> enter the seed, click the options buttton, select "BIP39" -> When prompted, leave the derivation path as: m/44'/0'/0'

(NOTE: This will recreate your Mycelium wallet... however, it will ONLY recreate the first "account" from Mycelium, if you had multipled accounts, things get a bit more complicated.)
- Once the wallet is recreated, you should be able to see all your transaction history, addresses and coins.
- Now send all your coins from their to the receive address from your new Electrum wallet.

All your coins are now in an Electrum "seeded" wallet.

I figured it out - I put what I ended up doing in this post: https://bitcointalk.org/index.php?topic=2456656.0
I will keep other suggestions in back pocket.
