Mycelium Bitcoin Wallet

[OmegaStarScream]

Your 12 word seed is what is used to create ALL the keys.  So, the number of transactions you have or backups doesn't matter.  It's always the same 12 word seed.

Private keys are generated each time you receive coins.  Actually, it's simply the next public key in the curve of your seed.

You never have to make a backup after the first.  So, if you lose the phone or simply want the wallet on another phone, you only need to install mycelium and restore using the 12 word seed.  Then, everything comes back (or simply clones) to the new phone(s).

In other words, the seed is able to generate unlimited amount of private keys? I would like to know something else, I contacted Bitaccess.co (a Bitcoin ATM) and they told me that their ATMs generate QR codes that contains the amount and that modern wallets should have the ability to read both the address + amount from the QR code, is that the case for Mycelium or not?

Each account have 2.1 billion (2^31) private keys according to BIP32. You would probably run into some other limit (like running out of memory on your device or something) first though.

It is. It understands QR codes which encode URLs of the format: bitcoin:<address>?amount=<amount> which is what ATMs generate.

Can you now specify the fee numerically as satoshis per byte? I stopped using Mycelium because I wasn't able to choose the fee other than picking between 4 too-high amounts.

Which wallet did you switch to?

No, you still have the just 4 options of "Low-Prio", "Economic", "Normal" and "Priority".

However it now seems to show the satoshi/byte rate and an approximate time which I don't recall seeing in previous versions. These are currently (20170408 2245 hrs UTC):

• "Low-Prio": >96sat/byte, ~3 hours
• "Economic": >109sat/byte, ~2 hours
• "Normal": >146sat/byte, ~30 minutes
• "Priority": >180sat/byte, ~10 minutes

I'll keep an eye on these and see if they update... They look roughly in line with what bitcoinfees.21.co would suggest... although btc.com seems to suggest only 40 sat/byte    Would make sense given the mempool count at the moment is less than 5000 unconfirmed transactions...

Did anyone else here invest in the MASS ICO because the name Mycelium was attached?

Mycelium acquired MASS, then ran an ICO raising over 300 BTC and now the Github repository has had no activity in 4 months since the ICO finished.

https://github.com/massnetwork/mass-browser

The lead developer Alexander quit the project, and when we ask Mycelium what's going on they are vague.

There was a telegram chat with at least 70 of the ICO participants in it, and one day the Mycelium team kicked everyone out of the telegram room and deleted it along with the conversation history.

"The mass guys are hard to get a hold of, you'll have to ask them" is an answer I received when I asked what was happening with MASS.

Um... isn't Mycelium "the MASS guys"?

There is a shitty browser on the Google Play store which appears to be a bare bones version of chromium with a window that tracks your browsing time to give you MASS coins based on the amount of time you use the browser for.

Another response I got was that they are waiting fro 100K downloads before they do anything else on the project.

This project appears to be dead, and it would be great if the Mycelium team could either commit to moving the project forward, or start issuing refunds since there has been on activity in 4 months since the ICO ended in December 2016.

I wouldn't recommend investing in anything where the name Mycelium is attached
Those guy's are a guarantee for chaos

I was talking to the developers and community/product manager (Rassah) in Telegram a couple of days ago. GitHub repository seem to be active once again and they decided to not build the wallet from scratch, instead, they will be pushing updates on the current Google play account where they hosted the wallet and the GitHub repo.

I asked them about the Twitter account too, they said that their CEO (who is busy with not sure what) is the one controlling the account and Rassah too but he have no updates to post and for the UASF then you got this: https://www.reddit.com/r/Bitcoin/comments/64xspk/mycelium_uasf/

are there any cell phone wallets where you do have control over the fees? i wonder if fee control is a hard thing to integrate because it doesn't seem very common.

A poor decision if you can then no longer use mobile apps to send/receive bitcoin.  Did you find an alternative that allows you to directly enter how many Sats you wish to pay?

Personally, I would rather have the option normal, quick, super quick confirmations than an app asking me the exact amount of satoshis to use for a transaction.  Far often than not, I have to put up with people picking an amount next to nothing and then bitching for 24 hours that their transaction isn't confirmed.

People complain that bitcoin is too complicated, but when made easier, they complain about not being able to control it to the point where it's not usable.

Using language like "normal", "quick" and "super quick" is a "Bad Idea"™. As that would be setting user expectations without being able to guarantee you could actually deliver. Even the use of "Low-Prio" and "Priority" is a bit iffy as there are no guarantees with BTC.

If you use the "Super Quick" value... and then 30,000 transactions get dumped onto the network that all have double your fee... how "Super Quick" do you think your transaction is actually going to be? Then you will have all the users who don't understand BTC and the blockchain properly, moaning that your wallet is too slow and X wallet is much faster.

And if you think I'm being unrealistic, check out the historical mempool count... There are massive spikes all the time.

Honestly, I think the best solution is just provide "advanced" settings, that would let the user specify. Electrum on the desktop lets you do it... if you want, otherwise you can just use dynamic and it will try and calculate the "best" fee according to their algorithm. The Electrum Android client lets you specify the fees in the settings, but has a minimum of 0.0003 BTC/kB (~ 30 sats/byte) and a max of 0.0003 BTC/kB (300 sats/byte) going in 0.0003 increments (or you just use the Dynamic option, which I believe takes fee estimates from the Electrum server)

Mycelium could easily just incorporate a "fifth" option on the fee level button that says "Manual" and enable a textinput box that would let you just enter an amount. Maybe throw up a toast message warning if it is below what it considers to be "normal".

I've been looking at the code on github, and would give it a shot, but I don't have access to an Android build environment to try it

I think you missed the point.   I want exactly what mycelium provides.  4 simple options.   If you let someone pick a specific amount,  it causes WAY more hassle than needed and simply leads to people bitching that their TX doesn't confirm and/or they paid too much.

Yes, mycelium 'could' give an 'advanced' option and let the user specifically screw up the fees to the point that a tx doesn't get confirmed. If the option is there, someone will use it and they will screw it up and they will complain about it.

I didn't know Electrum had a mobile app.  Thanks.  Downloading now.

Then that is "User Error" and you cannot blame the developers. Much like you can't blame gun manufacturers for people shooting other people "accidentally".

At some point, people need to accept responsibility for their own actions and mistakes.

The way I see it, if someone has a manual fee box, and they specify 1 satoshi/byte and then ignore a warning message that it is a low fee and could take a long time to confirm and go ahead and click "send" then they have no right to complain about long confirmation times and deserve 0.00 units of sympathy.

However, as a relatively intelligent person, I don't see why I should have to have my choices limited because the developers are aiming at the Lowest Common Denominator. Give me advanced options and let me accept responsibility for watching the mempool and waiting until there are less than 3000 unconfirmed transactions before sending my 10 satoshi/byte fee transactions

[Michail1]

Then we completely agree.

Again, thanks for the Electrum idea.  For some reason, I never bothered to check if there was a mobile app.

Cheers.

What are you guys using then?

[hgmichna]

I think there should be an additional setting, "Risky, may never confirm". Since four choices are too many, I think the lowest-fee setting should be repurposed for "Risky".

But actually I think an even better solution would be to show the confirmation time ranges or at least confirmation time averages that a certain fee would have achieved during the last 7 days, along with a warning that the future is unpredictable. That could be a slider with markings for satoshi/byte. The slider could have a red, a yellow, and a green range for risky, slow, and fast settings.

Your customers are your best designers. (:-)

For mobile, I use Mycelium almost exclusively - android and iOS (although the iOS version needs an overhaul, it still works fine).
I also use breadwallet on iOS.   Never thought to even lookup Electrum on mobile until it was brought up yesterday (Android yes, but not available on iOS).

I've been known to use blockchain.info wallet app as well - until I can finally rid myself of coinbase tracked coins.

For desktop (laptop), I only use Bitcoin CORE wallet (full node).
