If someone were to steal my phone, what would be the fastest way to use my backup to recover the coins without another android device?

You have to send the bitcoins to another wallet before the thief does.

Note that it may take the thief some time, because he first has to cut through your protection, like a 6-digit PIN.

For this you need a computer or smartphone. With a Mycelium backup the easier route is to use another smartphone, install Mycelium on it, restore the backup, and send all bitcoins to other wallets, for example to new wallets you create.

You could ask a trustworthy friend with a smartphone to do it for you, if you cannot obtain another new phone quickly enough.

There is a way to restore the wallet to a computer from the Mycelium backup, but I believe it is much more work.

My question is, if I ever lose my phone, it's stolen, or anything else happens where I need to use the backup PDF document I created in a fresh installation of Mycelium, will the restore procedure always restore the most current amount of bitcoin associated with that address, or is the backup a snapshot of whatever the balance is when the backup is made?

You only need to backup once. Restoring to a new phone with a new install of Mycelium will show the full _current_ balance of your coins. (It goes to the p-p ledger/blockchain to look up your balance.)

The backup does not even contain the number of bitcoins in your wallet. It only contains the essential wallet information, i.e. private and public keys.

How many bitcoins are in your wallet is determined by the public ledger, the blockchain, which is stored on all full bitcoin clients (including the Mycelium servers).

Remember, you could still use the wallet from another computer or phone and send bitcoins from it. Likewise, anybody could send money to your wallet at any time, which does not require anything on your side, neither computer nor phone.

Your wallet receives bitcoins even if everything is switched off on your side. You would find those bitcoins as soon as you look at your wallet, which you could do on any web browser, for example on blockchain.info, if you type in your complete wallet address.

Hi,

I apologize in advance if this has already been asked and answered before (and also for the noobness of the question).  I tried searching, but wasn't able to find a definitive answer to what I would like to ask.

I installed the Mycelium wallet on my phone.  I created a PDF backup, then verified it (successfully).  This is all before I transferred any funds into my Mycelium wallet address.  I then transferred a small amount into it, and it's showing as successfully received.

My question is, if I ever lose my phone, it's stolen, or anything else happens where I need to use the backup PDF document I created in a fresh installation of Mycelium, will the restore procedure always restore the most current amount of bitcoin associated with that address, or is the backup a snapshot of whatever the balance is when the backup is made?  I doubt it's the latter, but need to verify and make sure.  If it was a snapshot, then that would mean I'd have to create a backup every time my balance changes, and that seems very cumbersome.  I hope what I'm asking is clear.

Many thanks.

Vlad.

Small request, to help us comply with the IRS's guidance on bitcoin it would be very useful if I could export the list of transactions in the app as a csv and upload it to Google Drive.

i only bought Samsung because i can replace the batteries.

I have 4 batteries and a separate charger. It is a life saver when your travel a lot. I never run into the issue of a discharged smartphone.

all the new phones have their batteries sealed inside. sucks and it is a ploy to make you buy a new phone every year since the battery is going to be designed to die soon.

My recommendation to all readers is to think hard before buying Samsung.

Too late, I already have one.

Anybody have any pointers to a thorough security checklist/site for them?

OK thx for the reply.

I did the back up with the pdf, wrote down the password and did the back up verification.

Hats off to Mycelium!

EDIT: i did as you said and I installed the mycelium application. By some chance, it has found the wallet :/

it was pocket change wallet.. so never bothered for a physical back up .... Sad partly my fault then.

Microsfot NEVER NEVER DID THAT TO ME.

Imagine you install a Windows update and you find applications and application data DELETED. WTFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFf ARRRRRRRRRRRRRGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH. I HATE GOOGLE.

I lost nearly all my bloody applications. 6 months of installations and search.

Google pushed the kitkat 4.4.2 upgrade on my Galaxy S4.

The mycelium application was deleted. Did I just lose 300$ because of Google shitty kitkat update? The update delete 50% of my installed applications!! It never told me anything about it. Sad Sad

Please help me!

Install Mycelium again and scan in your wallets from the backup printout.

By the way, unless your phone was a Google Play Edition, the new version was pushed by Samsung, not by Google. And Samsung is known as a low-quality company that fills your phone with bloatware, replete with severe defects and security holes that are not repaired by Samsung for very long periods of time. What just happened to you may be a typical example for this. My recommendation to all readers is to think hard before buying Samsung.

Hi! I am currently testing the Mycelium on my phone. Sorry if I am dumb, but I can't figure out how to send BTCs from multiple addresses to multiple addresses?

Is there a way to zero the fee when the transaction size and maturity does not require any? Its more a problem of destroying rounded values when fee is subtracted than the fee itself.

Just hitting back and getting to the main wallet screen is enough to wipe the Cold Storage key from memory.
the key is also deleted if you finish the wizard successfully.

When will you add the “Transaction Confidence” graph to the standard wallet for everyday use and not just for trading?

After we release Local Trader. For now we don't know enough to be more specific than that.

what's the proper way to close Mycelium to wipe the key from memory?

Bug / Feature Request (not sure which!)

When sending without a network connection, the 'recipient address' page should not go away and the error message should stay until the user acknowledges it.

To Reproduce:
  • Be connected to the internet on your mobile
  • Click Send
  • Obtain the details (scan qr)
  • Activate flight mode (ie simulate network loss)
  • Press send
  • Enter pin

Actual result:
  • Small message with low contrast to background is flashed as an alert, which goes away after a couple of seconds - very easy to miss
  • Return to 'balance' page
  • No record of failed transaction anywhere

Desired result:
  • Return to 'Recipient Address' page with previously scanned details
  • Show a message with strong colours that it failed, which does not go away until the user makes it go away
  • Show a network connectivity indicator when this happens, so the user can know when they should retry the transaction

The reason I request this is because when at a shop, it's easy to get excited / distracted and 'just hit send' then not pay any further attention. The behavior between "tx worked" and "tx didn't work" is far too similar and can very easily lead to confusion.

I know that the 'Send' button cannot be clicked to initiate a qr scan unless the user is connected, but it's not too had to imagine an internet disconnection between the time between pressing that button and actually trying to broadcasting (which is a non-trivial amount of time, especially considering the time to scan a qr and enter a pin)

I predict that there is going to be an immense pressure on wallet developers to lower the fees with 0.9 out.

To me it seems that people want to do micropayments with bitcoin. Now they bump against the fees, but if the fees are lowered, they may well bump into the next obstacle—the block size limit.

If that gets raised too, miners will bump against excessive blockchain bulk, and everybody will bump against performance limits. Satoshi Nakamoto's original design was extremely well tuned. It cannot easily be stretched, at least not very far.

One could try to redesign bitcoin, like demanding a transaction for each wallet every 2 years, then deleting all blockchain content older than 2 years. But such a redesign would raise so severe problems that I am almost certain that it will not happen.

Perhaps one way out is to build a micropayment system on top of bitcoin. One possibility would be a system that moves small IOUs that are regularly consolidated and settled with real bitcoins, like once every 24 hours. Such a system might have to contain a trust network and would not be very simple. But to build it might well be a good way to earn a living and some fame.

Another way out that I can imagine would be to invent and change over to bitcoin 2, which would have to be so cleverly designed that it surmounts these problems. One system I could vaguely imagine would be to have hundreds or thousands of bitcoin-like blockchains that are basically separate from each other, but are kept in line by some kind of arbitrage between them that guarantees that prices will be very nearly equal.

Who knows? I gladly admit that my ideas are very vague and unripe.

ETA on Mycelium with the new standard fee?
The new fee rules in 0.9 affect the default relay fee rule, but not the default miner fee. This means that your transaction will propagate with a lower fee, but not necessarily confirm.
Until now the default relay fee rules and default mining fee have been the same. It remains to be seen how the miners react.
If we lower the fee right now we will probably get a lot of unhappy users (blaming our software) because nothing confirms. 0.9 is just out and it will take some time until it has proliferated, and we will have to see whether miners actively set the mining fee below the standard.

I have no problem with a base fee of 0.0001 BTC

Even at $1000/btc, that's only 10 cents (U.S.) per transaction. At current prices, closer to 6 cents. Still cheaper than a bank wire, and worth it for anyone not trying to make micropayments (which Bitcoin really wasn't designed for anyway.)

While saving coins is always a plus, don't feel rushed to lower the fee anytime soon. Smiley

We agree on many levels. Thanks for the support.
