uno makes me such paranoid
about encryption / backups  

if you let's say send 10 LTC/BTC/UNO/... to your adress you have one input with 10. Now you want to send only 2 out. If you check on the explorer in most cases the 10 are gone and the remaining 8 go into a change-adress which you do not directly see in the GUI.
I noticed this first time when i noticed a difference between my actual hotwallet ballance and what the explorer showed. Not many know it apparently.

If you have large inputs and small outputs (you receive a lot at once but only send out small amounts) there can end up quite a bit in those change-adresses.

Best is to say: make a backup from time to time or if you're paranoid about loosing coins every time you have sent coins but that's also where the sense for a hotwallet comes in.

Well, never stop learning apparently 
I'm sure there's other reasons to backup as well, signed messages I think? Just... Backup

@backup: each time you send coins it creates a change-adress where the change gets in (inputs and outputs don't match each other). That's a new adress which you don't see. So it is recommended for 100% security to back up after each send. That way you will not even loose a fraction of a coin.

@market
lol, that guy with his 280. He must feel bad. He's moving it down where ever but at the same time doesn't realise he's the only one interested in selling that low  
And of course he needs to sell in one order. 

Well, transactions don't matter as those are stored inside the blockchain. But if you add or remove a send or receiving address, then yes, backup! The sending addresses don't matter much, but if you have a bunch, then having to re-enter them at some point sucks

Also, NEVER keep an un-encrypted copy around!

If you create a new wallet, the initial wallet.dat will always contain the first receiving address, un-encrypted. Suppose you back that up and then encrypt the wallet.dat, and back that up as well. Now you send 100UNO to your default address, thinking you are safe because the wallet has been encrypted. But the original wallet.dat still exists, contains the same private key and is not encrypted.
Anyway, now you have 100UNO in the first address. You add a second address and send 15UNO to that. And someone else sends you 20UNO to your first address.
You wallet shows you have 135 UNO. You backup the wallet (do it once in a while anyway)

Now someone finds your unencrypted wallet.dat and imports that into his wallet application. He now has full access to the original address as that is stored inside the wallet.dat without password or anything! After syncing he sees 120UNO and sends them to another address. You lose the coins! Your wallet will show the transaction, 120UNO out, and 15UNO remain because the un-encrypted wallet.dat does not contain a private key for the second address that was added later so the thief does not have access to that.

Hope this sheds a bit of light on the importance of encryption and backing up

Hey, Mike.

I gotta get this clear: back up dat file on at least two usb's after every transaction?

Good you can save a large part of your time and effort spent on building the future


As for backup, create a new wallet, encrypt it, and then back it up. It doesn't matter if you have coins in there or not, what matters is that you have a backup of the keys. Once you have those, you'll always have access to the coins as coins are stored as transactions inside the blockchain. So, it's important crucial to backup after each address action.

14 days low: 0.0072
14 days high: 0.00801

low volatility, which is good in the bigger picture.

The 14-days-low was 14 days ago, the high was today and last days which means we are on the up.

buysupport could be a bit better but ok, nothing is perfect. Can come in any minute, who knows.
The fudding took away a bit of support yesterday. That needs to be replaced.

if gains don't happen immediately people tend to run away on to the next bandwagon. This behaviour fails on a greater scale of course. Most people around here are quite young and impatient. Uno community is one of the more solid, active and positive ones. Also higher average age than most other coin. I think it has to do with the coin, too. Uno is pretty simple and doesn't start to sweat over so called 'innovation' because it doesn't compete on that level so much.
Being a fair longterm coin which it is gives it a more solid community aswell. Uno is not a flavour-of-the-week-coin

Got to say also: most other coins are suffering from heavy inflation which makes bearmarkets extremely painful. Attrition happens in those situations.

Which deserted, highly innovative and likely inflationary flavour-of-the-week-coin have you been at?  


(wanted to buy VTC today but figured it is still too high!)

One of the best posts ever.

@ Benefactor: taa. 'Tech support' is a great community strength.

@ Community: I had cause to be checkin' out on Bitcointalk a coin 'up the charts' from us -- over three times the market cap.  But there were only a dozen posts dated this month, and the community is in conflict. Can we spell the word 'attrition'?

If anyone in the community competently, directly helped you to recover your funds....

nice graphics prominer!

NO!  You backup the wallet BEFORE you add funds to it, but AFTER you have your receive address(es) that you will be using, and AFTER you've encrypted the wallet.  You test your wallet beforehand, too!

[edit:  **NOTE:  The following misses "change address" cases, see discussion on the next thread Page #204**; it also misses saving other data that I don't consider critical.  Also, I never send to the initial address created automatically in a wallet.]


This is how you should do it:


1.  Start a new wallet.

2.  Add a bunch of receive addresses, (like 20, more than you think you need for a loong time.)

3.  Download blockchain.

4.  Encrypt wallet.

5. MAKE A BACKUP.
5.5  Optional:  Make additional backups as needed and store in safe places.

6.  Test wallet by receiving a small amount, ( < 0.11 UNO.)
6.5  Test wallet by sending that amount.

7.0 Optional for long-term wallet.  (Ignore this step for your petty cash hot wallet(s).):  Create a list of the receive addresses, so you can send to them.  List must have addresses perfectly copied - no errors!
7.1 Optional for long-term wallet.  (Ignore this step for your petty cash hot wallet(s).):  Take wallet completely offline.  {Programs/Roaming/Unobtanium} move all directories if you know what you are doing!  Your cold storage wallet doesn't have to be online for the blockchain to know those addresses are receiving additional funds while it is offline.  Just check the blockchain, not your cold storage wallet, to verify you have the funds.  Worst case is you only need the private keys on your backed-up wallet.dat file.  (Also make sure you never get confused which wallet.dat goes to which wallet, and don't overwrite them, etc.)

8.  Optional, but mandatory if applicable:  If you EVER add a single new receive address or change the passphrase or de-encrypt, you need new backups.

9.  Send funds to existing, backed-up receive addresses, and enjoy your Unobtanium!!!

 
     I'm happy for brother Edgar and the recovered coins .....Thank's man!

have you tried opening the wallet.dat with an editor? IXC-wallets are normally not encrypted so the privatekey could be there in plain text maybe?
