Topic: Mycelium Bitcoin Wallet - page 69. (Read 586368 times)

I also have my text number in my ad with instructions in the ad description. Yet my trade history shows 4 stopped the trade, 1 timed out after I pasted the instructions in the chat, and 1 _I_ stopped the trade after they didn't respond to my reply.

I know they see the description when they click on the ad...

I was trying to confirm the "cold storage spending" feature and change return process with a simple test.  It did not work as I expected it to.  Hopefully someone can tell me what I did wrong.

I had an address with only 0.25 mBTC in it.  I used the Mycelium Cold Storage feature to spend from it.  I scanned the private key and had it spend 0.14999 mBTC to one of my Mycelium addresses, and a miner's fee of 0.1 mBTC.  I was expecting to see the remaining 0.00000001 mBTC returned as change to the same cold storage address.

Instead, what happened was that the 0.14999 mBTC went to my Mycelium address, but the miner got 0.00010001 mBTC.  So, was that new amount an adjusted miner's fee?  Or was the miner's fee still 0.1 mBTC, but the change of 0.00000001 mBTC go to the miner?

Or does this have something to do with the small dust levels I'm playing with?  If I was to spend a partial amount from my cold storage, how can I trust that the change will be returned to my paper wallet?

Thanks

Yes, that's bothering me too. Hope this will be changed soon.

I was just contacted, for the first time, through local trader by someone who wants to buy coins from me and something's wrong.  From what I can tell, he doesn't see my chat posts, and I don't see his.  Anyway, he answered my ad yesterday, I entered my phone number in the chat box and said text me.  Nothing.  So this morning, same guy answers my ad again.  I type my phone number and tell him to call or text. Nothing.  I cancel the order from yesterday, because now we're on a new one.  Then I see where it says you "may" get hit with a reputation penalty if you cancel a deal.  May?  Do you or do you not penalize?  What's the deal, does somebody at Mycelium flip a coin to decide whether to penalize each canceled deal?  And shouldn't it be obvious that sometimes you just have to cancel?

Edit:  The guy just answered my ad for the fourth time, and still no communication.  I put my phone number in the ad.
I want to put a stop to this.
Now I have this list of pending deals going nowhere, which I can't cancel for fear of damaging my reputation.  To top it all off, I had to deactivate my ad.

Local Trader needs to have a block function where I can bar clowns like this Leonardo guy.  And allow us to cancel without penalty.

That makes the crucial difference! 

We have not been approached by authorities thus far, and suspect they don't even know about us.
The situation might be different, since we do not hold user funds.
For now, no immediate action / changes will take place, but we will monitor what happens...

Over in the localbitcoins.com thread there is a report that users from Germany are barred (I'm guessing by using IP geolocation) from using the service since the money flow can not always be traced (cash deals). Has Mycelium been approached by regulatory authorities from Germany? What do you think about it?

Very nice
Eagerly awaiting...

Thank you

Coincontrol is not on our todo list. Our wallet is meant for personal daily usage, and automatically picks which addresses to spend from to minimize fees. Once we implement CoinJoin, coin control may even be a security issue that could expose the privacy of your addresses.

Here's the roadmap so far:

Allow lower transaction fees (currently in beta)
Support for Shamir's Secret Sharing keys, which are private keys that are split into m-of-n parts, as supported by Mycelium Entropy (currently in beta)
BitID support (currently in testnet)
Support for tor through nodes accessible over tor hidden services (implemented and being tested on the nodes)
Added functionality to LocalTrader, such as more control over trading logs, and improved reputation options, including reputation for buyers so they can be trusted to buy from sellers using more risky means.
More selling options on LocalTrader besides just bitcoin for fiat, such as bitcoin for other stuff you want to sell, similar to Craigslist
Support for CoinJoin (possibly later this Spring)
Support for Rivetz (when their API comes out in 2015)
Implement BIP70 (it's a constant medium-to-high priority that we just can't set aside the time to do)
Possibly support for other digital currencies
Long term, we hope to make Mycelium into a full fledged financial app, with support for transaction categories, exporting transaction history, monitoring spending, being able to use is as a merchant POS, etc.

will coincontrol soon be released? or  is it down on the list?

Any official roadmap link with the next features sorted by priority?

Thank you.

We only strongly advise against 2.2, that's why there is a big red warning. Other old versions get a notification that we will not put out updates for them (we will of course if we encounter critical bugs).
It's perfectly fine to continue using them including all features and HD. Our new releases will only support newer versions of Android, because it will be easier to code, work better, requires less permissions etc.

Mycelium warned me that there will be no further updates for my Android version.
So using Mycelium HD wallet functionality with this old Android is not recommended now? I can use old pre-HD address pairs.

I'm not 100% sure, but I think the move to BIP39 is in the upcoming 2.0 release (that also supports trezor).

Mycelium already supports this. The idea was to be able to use your phone to pay with bitcoin, using the merchant's connection to the bitcoin network, without the user even needing a data connection (for example if you don't have a data plan, have bad reception, or are traveling outside of your coverage area). This would need NFC for the merchant to send the request, and NFC or bluetooth (though bluetooth isn't typically available in payment terminals) to receive the signed transaction back.

Thanks, that sounds feasible. Will try the current HD address.

You cannot create new single addresses, just import them, because random single keys would not be backed up by your wordlist backup, and we want to prevent users from loosing money.

Your could just put up the current receiving address of your HD account.
As soon as you receive money to it, the app will display a new receiving address, but the old one will still work.
You can then replace the address with the new current one whenever you want to.

You could of course also create a new HD account, and use that one only for website donations, and replace the address with that accounts receiving address from time to time.

I would like to put a bitcoin address up on a web site for donations (and later change it from time to time). How can I do this with Mycelium? How can I create a new bitcoin address, either HD or non-HD, for this purpose?

My HD wallet already has several bitcoin addresses with zero bitcoins on them, and one possibility would be to use one of them. But Mycelium does not seem to display them. But even if I wanted to create a new non-HD wallet/address, I cannot find any way to do that with Mycelium.

I have not considered creating multiple HD wallets, because I thought that too unwieldy and impractical. I don't even know whether that would solve the problem.

What would be the most elegant way to do it?

You are right. You can do 1 device-to-device tap to pay as long as the Sender is broadcasting out the message directly to the network using their internet connection. Another way is to use both NFC and bluetooth (BLE) and tap to get URI and BLE communications key via NFC, then use BLE to talk to device and send Tx after.

Airbitz actually has the one tap method functional in our next release which should be out this week. Here's a video of it working

Ah, ok, this is indeed bad, thanks for the explanation!
So as upgrading the OS is not an option (Samsung isn't really eager to supply updates, and the phone isn't really supported by Cyanogenmod), I'm just waiting for the new phone. Whatever transactions I need to do in the meantime can be done with bitcoin core on my desktop.

there is a bug that leads to android 2.2 being unable to multiply big numbers _sometimes_. previously this mostly just lead to wrong TX being generated, that were rejected by the network. annoying, but no huge risk.

now with HD wallets it is possible to generate a wrong address from a seed that has no matching private key. this is bad. therefore, quit using it we had one case where a user reported this, and we strongly think android 2.2 was the reason.
