Thanks for the good answers! I think I understand the problem a bit better now.
In a normal HD wallet, after normal use, does each address not have exactly one UTXO?
Topic: Mycelium Bitcoin Wallet - page 18. (Read 586360 times)
When I send from an HD address, how does Mycelium select which addresses to send from?
Actually I would like to know whether I can influence which address is used by choosing a particular amount to transmit. For example, if I choose to send the exact amount of one of my addresses, will Mycelium then empty that address? How about the fee in this scenario? This would amount to some kind of indirect coin control. Would be nice to have.
HCP explained why that would be hard to do, with Mycelium lacking coin controlActually I would like to know whether I can influence which address is used by choosing a particular amount to transmit.

I think if you want to empty a particular address in your HD wallet, you should get the private key of that address and import it into a different wallet: a single-address wallet, not HD. Then you can send the coins from that address and that address alone. You could try using a Mycelium legacy address. It would probably work.
I haven't done it, so I'm not sure what's the easiest way to get the private key from an address in the Mycelium HD. If Mycelium HD doesn't show the private keys of individual HD addresses, then you will have to use an external utility that generates series of HD addresses from seed.
Here's an example of such a uility:

of course, you can't do that online with any expectation of safety, so you would have to save the web page and run it offline, or better yet download the code from github and check the pgp signature.
It's been a long time since I fiddled with this stuff. I seem to remember there are two kinds of address in the HD wallet, receive addresses (which receive external funds) versus "change" addresses, in which you receive funds from yourself.
You don't send from an address. You create a transaction that transfers control of a certain value of coins from one set of private keys to another set of private keys.
You can't really influence which UTXOs controlled by your wallet are used in any given transaction using Mycelium. It has no coin control features. If you try to send the exact amount contained in one address it won't work, as it will then need to use other UTXOs to pay the fee... at which point, Mycelium's algorithm may detect a better combination of UTXOs to use to minimise transaction size etc.

Nice bitcoin wallet for android devic.I want to know about to transaction fee from mycelium to mycelium wallet & mycelium to any other wallet charge.
Mycelium wallet isn't like coinbase that when you send some of your funds to the same wallet/client you will not asked for fees. Its a kind of wallet which will depends on the network, the recommended fee and the size of the transaction, so if you send to anyone you will required fees for every transaction, which will depend on how fast it will confirm buy choosing low prio, economic, normal and priority.

The fees you are paying are network fees, It's not like PayPal where fees change based on the country etc. so It doesn't matter who you are sending to or receiving from, they are simply based on the transaction size and to have them small, make sure your are not receiving too much dust payments.

Hi, running latest 2.8.12 (281201) here - Is anyone else able to add addresses to the address book? it looks as though the "add person" icon has been moved to the "Businesess" tab, but clicking on it does nothing at all.
Am I crazy? Thanks
Am I crazy? Thanks
You are note crazy, this has been reported in their GitHub repository and in their telegram channel as well, I believe it's fixed, It just need to be pushed, we must wait for the update.
Super, thank you, it was making me angry for a bit there!

Wow.
Wonder if mycelium wallet will sort both tokens if bitcoin slits

It doesn't really matter If they are going to support both or not, as long as you control your private keys, you shouldn't be afraid of anything.
When a Mycelium HD wallet generates hundreds of addresses, is that a good reason to create a new one from scratch, i.e. a completely separate new HD wallet?
Or does an HD wallet easily work with, say, a thousand addresses? How about performance?
If you have a thousand addresses in your HD wallet, most of them will be old, empty addresses that will never be used again. Generally, your wallet only works with the recent addresses that still have coins in them.Or does an HD wallet easily work with, say, a thousand addresses? How about performance?
All those old addresses only slow you down when you refresh the wallet, because it has to scan all of them. But you probably seldom need to rescan your wallet.

But this time Mycelium websites are down any ideas? 
Rassah said that they are moving nodes, that's why It's currently down. Subdomains are accessible though: swish.mycelium.com for example.
Yep. Me too. Maybe they can't be bothered to pay their server bills no more.
It's working just fine right now. I believe It was only technical issues but the sooner they make the SPV update that should let us make our own servers and connect to the better, just like Electrum is doing.

Yeah, this will be a great implementation.But this time Mycelium websites are down any ideas?

Thanks for your reply! I see that one of my old, non-HD wallets in Mycelium bears the green label, "(Local Trader account key)". That must be it then.
I deleted that wallet, but the Mycelium Marketplace still kept my Local Trader identity.
Then I found a function to delete my Local Trader identity and used that. And this was the solution. My trader identy was deleted, and I could create a new one while keeping everything that is unrelated to the Mycelium Marketplace unchanged.

What is the easiest way to change your Mycelium Marketplace name?
I suspect the only way is to create an entirely new identity by erasing Mycelium (after sending all bitcoins elsewhere or by using a second smartphone) and starting from scratch.
But please let me know whether there is a more convenient way.
According to the "how to trade"... Your Marketplace account is tied to your private key... so the only way to get that changed would probably be asking Mycelium support nicely, or generating a new "private key". I'm not entirely sure what private key they're referring to tho... if that is just the private key for a particular address, or the master private key for your HD wallet... I would guess the later.I suspect the only way is to create an entirely new identity by erasing Mycelium (after sending all bitcoins elsewhere or by using a second smartphone) and starting from scratch.

Mycelium Local Trader uses your bitcoin private key for registration and authentication with Mycelium servers. The only information retained by Mycelium servers is your bitcoin address, nickname, sell orders with the entered location, and your trade history

I'm the only one who is having a message saying "No server connection" at the bottom each time I open the wallet or refresh it?
