Specifying own change address equal to adding this address as additional destination to the transaction. Well, you need to calculate the remaining amount (this could be done by Mycelium anyway).
|

|
|
Bitcoin addresses contain a checksum, so it is very unlikely that mistyping an address will cause you to lose money.

After LocalTrader, our next big project will be HD wallets, so all of these issues will be taken care of automatically, with new change addresses generated every time.
Please consider leaving an option for the user to select his own change address. I like to generate my own private keys offline and track them on multiple apps. HD Wallets are fine but I'm hoping not to be locked-in to using HD generated addresses exclusively. we are not 100% sure how HD will be implemented, but the general idea is that it should become easier, for the user, as much as possible. is there a good reason for manually specifying a change address?

Change is always returned to whichever address you have selected as your default at the time
That pretty much answers every question I had and resolves pretty much all of my issues as well. If you just keep an empty address as the default it appears you are good to go. This is a great wallet. Thanks. Not 100% correct. Change always flows back the the address that contributed the most input. So if you have two unspent outputs on two different addresses and make a transaction that spends both outputs, then any change goes to the address that provided the most input. So why is that? If someone convinces you to import a private key that he also controls, then you will only send change back to it if it is the largest contributor. This way you never risk someone giving you a private key with 0.0001 and you send change back to it > 0.0001. For cold storage spending (the trivial case where there is only one address in play) it means that it always goes back to the cold storage address. Once we get to HD wallets we will have 1. Spending from HD wallet - change always flows to a new address 2. Spending from cold storage - change always flow back to your paper wallet 3. Spending from 'classic' addresses (the ones we have now)- change always flows back to the address that provided the most input. (2 and 3 follow the same rules actually)

Today my Mycelium app has _ONLY_ private keys that I have personally generated offline and added to Mycelium. Change will therefore only go back to one of my generated-addresses. I want that and like that. I know how my keys were generated and monitor them outside of Mycelium. My preference is to know each address that holds my coins. I can easily monitor them individually in multiple tools including simple web links to Blockchain. If I can still operate this way after the introduction of HD Wallets then I'm happy. If I can't operate this way after HD Wallets because Mycelium insists on internally generating new change addresses and using them then I will feel that the level of control that Mycelium gives me is broken. It will become difficult to track my coins. I know Mycelium will make it easy etc. etc. but by nature I prefer to be the one responsible for my keys.

I don't think I see an answer to this question-- Is it possible to transfer your trader profile and reputation to another address?

You cannot change the local trader address associated with a trader account. The encrypted trade history of your account can only be decrypted with the private key of the address the trader account is associated with.

In the wallet, one has the advanced options, beyond making all transactions on a single address. As you continue developing mycelium's capabilities, do you foresee enabling more advanced functionality in local trader? I aspire to building a reputation as a trader, and I wish to make many transactions in the coming years. Making all the transactions at the same address brings up privacy concerns. As you work to integrate HD in the wallet, in the same vein, please consider making improvements in the flexiblity of local trader; perhaps syncing local trader with the main wallet's HD, for example.

The thing that makes the Local Trader address special is that its private key is used for authentication purposes (using bitcoin message signing) and for encrypting the communication with the peer you trade with (using an Elleptic Curve Diffie Hellman variant + AES & HMAC). The address you send from or receive with depends on the currently selected address just when you send / receive funds with the wallet. So the transactions used for trading only occur with the local trader access if this is where you store your coins. You can even put the local trader address in your archive. Once we get to HD nothing will change from a Local Trader perspective, it just uses the wallet you have with its current settings. If it happens to be a HD wallet then it will use new addresses for receiving coins and change. Hope this clarifies

Hope this clarifies OK, so you can use addresses in local trader other than the address whose key is associated with the local trader account? If so, my concerns were misplaced.

Yes, you can perfectly use a single address only for login at local trader (this is the one which is associated with your username) and never have any Bitcoins on it. You can send and receive from other addresses in your wallet.

Hmmm, I heard about that. Wasn't that project stuck because of financial stuff?
From the Trezor thread: BitcoinCard (Mycelium) never took preorders, and never will. The delay reasons are "still looking for hardware advanced enough to fulfill our vision" rather than "had trouble with cases." What Mycelium is making is way more complex, but there is finally a finish line in sight... [...]
I also recall a post from Jan, saying something to that effect. Can't find it right now though.
