8181  Bitcoin / Electrum / Re: Electrum BTC Address Questions on: September 27, 2017, 02:48:41 AM
All movements prior to this -> Site Sending you BTC -> Your wallet -> Bittrex

That is effectively what Bittrex, and what the site sending you BTC, would be able to track... Having said that, theoretically, Bittrex can't know for certain what the addresses prior to yours are unless they have extra info... likewise, the site sending you BTC can't know for certain what the addresses AFTER your address are without extra info... you could just be moving coins amongst your own accounts, or sending them to other people or using a bitcoin mixer or...

In all honesty... your desire for anonymity is somewhat misplaced with Bitcoin... it isn't as anonymous as people like to think... and blockchain analysis companies exist for a reason... like I said, go use Monero if you are super concerned about anonymity...

Send Monero to exchange... trade it however you want within the exchange... send it back to your Monero wallet if you're concerned about storing funds on an exchange for an extended period of time.

If you can't get around the "receive BTC from site" part... just send the BTC via a mixer to the exchange... trade it how you like... then back into Monero and into your Monero wallet...

Otherwise, if you're just sending BTC around, pretend like you have 0 anonymity... because as soon as you rely on it being "anonymous", you're like to get into trouble.



8182  Bitcoin / Electrum / Re: exporting private key from wallet with 2fa on: September 27, 2017, 02:36:52 AM
2FA wallets are "MultiSig" wallets... so the address is actually created using THREE private keys... exporting a single one and then importing it into another wallet will generate a completely different address and you will not be able to access your MAID token.

From a quick read, you would need to manually construct a "raw, unsigned" transaction that transfers your MAID... and then sign it with Electrum by getting the 2 private keys for your 2FA address from restoring and disabling 2FA.

Read this: https://github.com/OmniLayer/omniwallet/issues/1314

They seem to have been successful in recovering MAID from an Electrum 2FA, but it looks like a LOT of work Undecided
8183  Bitcoin / Electrum / Re: Problem with google authenticator in Electrum on: September 26, 2017, 11:20:41 PM
Make sure that your phone date/time is correct. It sounds like it might be out of sync. Google Authenicator should have a "resync" option:

Open the Google authenticator app
* Click the menu button of your phone
* Choose settings
* Choose Time correction for codes
* Choose Sync now

The app should now sync it's time with the Google servers instead of your phones internal clock.
8184  Bitcoin / Electrum / Re: Sent Bitcoin cash via Electron Cash wallet but only received fractional amount on: September 26, 2017, 11:17:13 PM
Double check the units being used... by default I believe that Electron Cash is set to "mBCC" or milli BitcoinCash units... so you would have sent like 1/1000th of the desired value of BCC Wink

"Tools -> Preferences -> Appearance"

Change the "Units" to "BCC" and you'll see that your original transaction amount is adjusted accordingly Wink

NOTE: Due to an existing bug, you will probably need to click close and then reopen the "Preferences" window and go back to "Appearance" tab to be able to set the decimal points to "8", after changing from mBCC to BCC units

The best part is that apparently he was never actually accepted into the sigcampaign... looks like just another account buying, shitposting, sig spammer tbh... Roll Eyes

He'll be lucky if he doesn't get tagged by the DT's that are against account sales... that would totally ruin his chances of getting into a sigcampaign Tongue

8187  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: September 26, 2017, 09:18:48 PM
What's wrong with just using Mycelium's 12 word seed as a backup? That is what it is designed for... Why do you want to use the xprv as your backup? Huh

The 12 word seed is much easier to write down and type back in should you ever need to restore your wallet... plus, it backs up ALL the different HD "accounts" within Mycelium (if you have created multiple accounts)... Simply click the "3 dot" menu and select backup.
8188  Bitcoin / Electrum / Re: MultiBit HD Wallet to Electrum on: September 26, 2017, 01:22:35 PM
First thing to check, is that you are using a ZERO character... and not an O.

Secondly, are you literally typing to make it "m/0'" or are you trying to use just: m/0'

It should NOT have the " characters... it should just be 4 characters... m / 0 ' with no spaces... try copy/pasting this:
Code:
m/0'
8189  Bitcoin / Armory / Re: BTC did not transfer from exchange to my Armory wallet on: September 26, 2017, 01:09:47 PM
I downloaded Armory (ver 0.96.3-beta-2b65ac0648) on a Windows 10 computer.
Did you also download, install, setup and fully sync Bitcoin Core? If you didn't, this is why you cannot see your bitcoins.

Armory relies on a fully synced Bitcoin Core Node to be able to send/receive transaction data from the Bitcoin Network.
8190  Bitcoin / Mycelium / Re: Noob Question! Just bought some Bit Coin via Mycelium app!! on: September 26, 2017, 01:05:29 PM
Probably using the incredibly expensive "Buy" feature in Mycelium that redirects to "Simplex". (https://mycelium.simplex-affiliates.com)

Aside from being incredibly expensive (has a markup of like 5+% or something ridiculous)... I don't see anywhere in the checkout form where you are supposed to put in your Bitcoin Address, so I have no idea how it figures out where to actually send your bitcoins!!?! Huh

Try and contact Mycelium and/or Simplex support and see if they can help...

8191  Bitcoin / Bitcoin Technical Support / Re: İ need help full node bitcoin core on: September 26, 2017, 11:00:27 AM
If you set Bitcoin Core to use D: as it's data dir when you did the install... then you need to find where you wallet.dat file is on D:

That is where you need to create "bitcoin.conf" file (it is just a text file)

Also, you don't "need" a config file, they're just useful for setting commandline options if you need to use them, but it isn't required for the application to run. If it isn't running properly, then you'll need to post the Bitcoin Core debug.log file so we can see what the exact error is

NOTE: Do NOT just post the contents of debug.log here... it probably won't fit in the max post size... instead use www.pastebin.com and just post the pastebin link here
8192  Bitcoin / Bitcoin Technical Support / Re: Missing outputs. Core shows different balance than block explorer and Electrum on: September 26, 2017, 10:52:49 AM
It's a change address... and it sounds like your friend has only exported the keys for the "Receiving Addresses" listed in his wallet.

You can locate ALL the addresses that contain coins (including change addresses) in Bitcoin Core by using the "listunspent" command in "Help -> debug window -> console"... once you have all the necessary addresses, use the "dumpprivkey" command in the console to get the private keys and then import them all into Electrum.

Your friend should then see the correct balance.
8193  Bitcoin / Armory / Re: Armory+Core+Win10 - How I made it work on: September 26, 2017, 10:16:22 AM
The odd is that they are talking to each other because the node is update... but stays offline
Then they are NOT talking to each other. The Node is completely separate from Armory... If it is launched (via Armory or manually) it will most likely update and download blocks from the bitcoin network, regardless of whether or not Armory is successfully retrieving information from it.


Quote
Indeed, just tried to send an amount and the transaction failed
I have the latest version of both, Core and Armony, on Windows 10
Can you suggest me a way of making things work ?
I honestly tried so many things to get it working, like manually launching Bitcoin Core, then opening Armory... it would sync to current block but would not get new blocks. I tried running Bitcoin Core using "listen=1" but that opens your Node up to incoming connections and drastically increases bandwidth usage as you start sending data to peers etc...

My suggested way is in the OP... if this did not work for you... then I can only suggest posting your armorylog.txt and dblog.txt logfiles into your own thread asking for help...
8194  Economy / Service Announcements / Re: [ANN] ChipMixer - mixing reinvented on: September 26, 2017, 10:05:02 AM
... every experienced programmer/user knows that with java script the programmer/administrator could steal your cookies (from any website) and forcing users to perform actions that they did not intend (IP LEAKING?! and much more) very unsafe for a mixing service.
I'm assuming you actually mean... "very unsafe for USERS of a mixing service"

But my question would be, why would the programmer/administrator need to steal cookies from users? The users are voluntarily giving them BTC... Who cares about some IP addresses and cookies when you can just wait until you get given a bunch of BTC and walk away... why hack your own JS? Huh

I see that the other site utilises PHP... a quick perusal of google using words like "php" and "vulnerability" cough up an awful lot of pages regarding security flaws in PHP... just like there are many ones about JS... At the end of the day, you are putting faith in any 3rd Party service that they have used appropriate methods to secure their systems, regardless of the systems in use. Using the "safest" system in the world isn't any good if you leave the door unlocked Tongue

Also, while it is a great show that they've put 10 BTC in escrow... aside from the word of the mixer admins and the escrowing party, is there any real way for them to actually prove that they are actually independent of each other and they're not best friends (or the same persons)?

8195  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: September 26, 2017, 06:56:33 AM
Mycelium will either let you backup/export your master seed (ie. 12 word seed mnemonic) or a "Master Private Key"... aka "xprv".

I'm fairly certain it doesn't dump the individual keys for each address in your HD account... Does the key you see start with "xprv"? If so, it is a Master Private Key.
8196  Bitcoin / Armory / Re: Armory+Core+Win10 - How I made it work on: September 26, 2017, 06:53:46 AM
After this setup, in Armony down at the right side, the node is meant to be online or offline?
It *should* say "Connected" in green... and show the current number of blocks that Bitcoin Core node is synced to. If it doesn't then it is possible that your Armory and Bitcoin Core are not talking to each other correctly...



Quote
If we try to send a transfer, it will take place or not if the node is offline (but nodes are updated through the core wallet)
Armory relies on the Node to be able to send and receive transaction information... if the Node is "offline", you will not be able to send a transfer as there is nothing to broadcast the transaction to the network.
8197  Bitcoin / Hardware wallets / Re: Ledger Nano S - Quick but very important question on: September 25, 2017, 09:12:47 AM
Best to think of it as multiple "apps" on your ledger...

You add and/or remove them using the Ledger Manager:


The Ledger Nano S is somewhat space limited and you can only have 4 or 5 "apps" loaded at once, however you don't "lose" anything if you uninstall one of the apps and then reinstall it... UNLESS you reset the device... All the "apps" use the same seed as the base for creating their addresses etc... so you can uninstall the BTC one, install LTC, send/receive LTCs, then uninstall LTC and reinstall BTC and continue from where you left off...

It can be a bit of a nuisance if you use a LOT of different supported coins... but it isn't impossible.
8198  Other / MultiBit / Re: Accedently changed the preference for opening wallet to Word. How to fix it? on: September 25, 2017, 01:19:42 AM
MultiBit Classic is VERY old... And hasn't been supported for quite a while. It's possible that it isn't syncing properly anymore (I'm not 100% sure if it uses custom servers or not)...

On the plus side, exporting your keys from MBC is very easy... And you can then sweep/import the keys into your new wallet...

Under "tools", select the "export private keys" option... When you do, DONT set a password on the output file, otherwise you won't be able to open it and read the private keys as it will be encrypted:


As you want to send to Bittrex, I don't think you can import, so you'll have to setup a sweep transaction. You could use Electrum to do this...

Either setup a new Electrum wallet and select "Use public or private keys" when selecting the type of keystore and then import the private keys from MBC and then create a send transaction to send all your coins to Bittrex...

OR create a new wallet in Electrum... Doesn't matter what type and then use "wallet -> private keys -> sweep" and set the address to be your Bittrex deposit address...

Both options so effectively the same thing, but the first option will give you greater control over the fees etc.
8199  Other / MultiBit / Re: Accedently changed the preference for opening wallet to Word. How to fix it? on: September 24, 2017, 09:23:58 AM
HCP- You might well be right that is the multibut program itself, I don't know.
I have multibit 05.15, not Classic
There was just one transaction made at all with this program and from this wallet . I has been sitting  there since 2013 . The O.01 BC transaction was to test. There is 0.9989 BC in wallet

I can see the balance in the loaded wallet in multibit. Above is the notice that I have 0 to spend.
If it is a multibit problem what can I do?
Are there any suggestions that might be helpful?
I'm a bit confused... Multibit 0.5.15 is MultiBit Classic... does it look like this:


or this:



If it looks like the 2nd one, you can import your seed into Electrum (click Options and select BIP39 Seed and use Derivation Path: m/0' when prompted)
8200  Bitcoin / Bitcoin Technical Support / Re: "Not enough memory" error while syncing blockchain with bitcoin core on: September 24, 2017, 08:53:51 AM
Did you actually set Core to store the blocks on your external drive during the install/setup process? If you didn't it will default to C: drive... specifically your "C:\Users\USERNAME\AppData\Roaming\Bitcoin" folder.

Could also be an out of RAM issue... Do you have other apps running?

Post the Bitcoin Core debug.log
