Mycelium did a double spend today on me. I sent a payment and it tried to broadcast the same transaction twice about 8 minutes apart from each other. The second transaction was nullified by the network as a double spend. Thought this was odd. Checked back and my balance was incorrect, couldn't get it to correct even after refreshing. Had to uninstall Sad

Has this happened to anyone else?

can anyone tell me how i can change my local currency from USD tu Euro while using localtrader?

i have created a trade in germany and want to sell bitcoins for Euros, but i can't change the USD button to any other currency.

i am using the mycelium app with an android emulator (bluestacks) on my computer

Be careful using bluestacks, it can be very unstable. Make sure you have a backup of your phrase before you start receiving bitcoins.

thank you very much for your quick reply.
after finding out how the settings button on a smartphone display looks like (i never used a smartphone before), i also found and changed the currency settings.
i just oversaw the option button...

Have you selected EUR as a currency in "Settings" for "Local currency"?

Now that the 2.5.0 is out, are you thinking about adding other supported currencies on Coinapult?

That would be up to Coinapult to add. We'll implement it whenever they're ready. In the mean time we have something else much bigger in store...

Sounds interesting, care to share some more information?

Feature request: Under Settings -> Currency, can we get "None". Sometimes I do not want/need the exchange rate displayed.

yes, this is planned for the next version. you will be able to select any number of fiat currencies, including 0.

I know work has been done on this since the above, but I still would like a currency option "none". That way I could cycle through USD, EUR, "none", depending on the situation. I realise I could go in the settings and remove the ticks, but it is rather tedious.

Will you add support for other currencies than USD on coinapult? (Ex: EUR...)

You could check that the addresses the webpage shows match the receiving addresses shown in your wallet app. That way you don't need to risk any funds.

I guess if the bits don't arrive in your wallet you can always just import the corresponding private key into bitcoin-core or some such to retrieve those bits.

I tried sending some bits to a couple of the addresses on the list and they didn't show up on my wallet. idk its pretty weird cuz the list shows like atleast 200 addresses when in the wallet ive only created like 3. i dont really know HD wallets work, anyways thanks for your help.

Oh, well the list is infinite... You can keep generating addresses forever.

The way it works is that your wallet generates the addresses in order, and looks them up one at a time on the blockchain. When it finds N in a row that have never been used, it stops looking. N is probably 5 or 10 or some small number like that.

So if you funded the 100th address, your wallet won't have bothered looking that far ahead.

I made a change to https://dooglus.github.io/bip39/ so it will let you know if the xprv key you enter is invalid, rather than just saying "Calculating" forever.

it seems to have worked it gave me the private keys, going to try sending some bits to one of the address shown on your site and see if they show up on my HD wallet.
o btw the derivation path shows as m/44'/0'/0'/0/y where y is the only number changing, i guess that makes sense cuz its 1 wallet.

do you happen to know how to get multiple private keys for a wallet if i have the extended private key (xpriv).

I don't know any easy way of generating the keys from an xpriv - it would be nice if https://dcpos.github.io/bip39/ allowed us to edit the xprv field ourselves. I'll look into making that change.

Try this:

https://dooglus.github.io/bip39/

I made the xprv field editable. I can't promise it works right, and the error handling isn't good at all. Click 'generate' then edit the xprv, and it won't tell you the value is invalid, it will just say "calculating" forever. But paste in a valid xprv code and it seems to work.

Edit: I made a pull request in the dcpos repository for this change to be merged into his site too: https://github.com/dcpos/bip39/pull/16

is that only compatible for mycelium phrases or can i use other hd accounts phrases as well?
and do you happen to know how to get multiple private keys for a wallet if i have the extended private key (xpriv).

It works with any wallet that uses BIP39 seeds, and BIP32 derivation.

Mycelium uses "m/44'/0'/x'/y" as its BIP32 derivation path, where x is the account number (starting for 0 for account 1, 1 for account 2, etc.) and y is 0 for receiving addresses and 1 for change addresses.

Other wallets use different strings.

You can use the BIP32 tab at https://dcpos.github.io/bip39/ to enter any BIP32 derivation path you like. If you put m/44'/0'/0'/0 in there, then you'll see the Mycelium receiving addresses for account 0 (what Mycelium calls "account 1"). Apparently hive wallet uses "m/0'/0", and other wallets presumably use their own version. You can play about with the BIP32 derivation path field until you see your receiving address being generated.

Thanks for explaining the derivation paths Cheesy

makes alot more sense now. i tried it with mycelium wallet and it worked like a charm.
This site deserves more attention.

Anyone having issues with the iphone version of mycelium? I use the android version. But I know a guy with the iphone version who loaded bitcoins to his wallet and has a zero balance showing even tho the coins show several confirmations in his transaction history. So the coins show as confirmed but he can't spend them. I found a reddit thread about how the iphone version is totally different, made by different devs and generally crappy. Any tips for this guy on how to access his btc?

Here's the reddit thread:

https://www.reddit.com/r/Bitcoin/comments/36ke99/mycelium_iphone_vs_android/

EDIT: If this issue is not resolved, is there a way to export the private keys from his wallet and spend the btc from another wallet?

You can export the master seed, and use that to generate the private keys.

Putting the 12 word seed into https://dcpos.github.io/bip39/ should get you the keys you need. You might want to load the page, then disconnect from the Internet if you're worried about the page somehow stealing your seed. Or even copy the page to a USB memory stick and load it on an entirely offline machine, depending on how safe you want to be.

You should see the receiving addresses shown by mycelium under 'derived addresses' on the BIP44 tab once you've entered the 12 word seed. If not, try changing the account number to 1 or 2. And if you change the 'external / internal' from 0 to 1, you'll see the change addresses instead of the receiving addresses for that account.
