13261  Bitcoin / Project Development / Re: Wallt.co - Create a simple, shareable page to list all of your wallet addresses on: January 17, 2018, 06:57:16 PM
After I login (and if I don't have any address), I get this error message at the top of the screen:

Code:
Notice: Undefined variable: result in /home/mediasit/public_html/wallt.co/includes/class/main.class.php on line 137

And this one at the bottom of the page:

Code:
Warning
: Invalid argument supplied for foreach() in
/home/mediasit/public_html/wallt.co/includes/templates/default/dashboard.php
on line
10

You should also add an "active" class to the navbar link which page you are.

Ok I'm dumb. I swear I thought this was Mycelium (for some reason) Tongue

Anyways, the method should be almost the same. That's what you will need to do in this case:

1. Open your wallet;
2. Click at the top of the screen where it shows "name_of_the_wallet" and your balance;
3. Click "Show seed" and enter your PIN;
4. Write down the seed;
5. Now download Electrum[1] (for PC) and open it;
6. When creating a new wallet, select: Standard Wallet -> I already have a seed -> Write the 12 words the Electrum android app showed to you;
7. If everything went well, you will see the same addresses and balance (plus the missing coins) you see in the android wallet.

Ok.. There is something I haven't seen until now. You are using Mycelium, right? Because you posted this in the "Electrum" board.

Try to do this:

1. Go to your Mycelium app and select your wallet;
2. Click the three dot menu at the top-right of the screen -> Backup;
3. Mycelium will probably start showing you words. Save them;
4. Now download Electrum[1] and open it;
5. When creating a new wallet, select: Standard Wallet -> I already have a seed -> Write the 12 words Mycelium gave to you;
6. Click Options ->Check "BIP39 Seed";
7. If everything went well, you will see the same addresses and balance (plus the missing coins) you see in Mycelium.

can we see the history of transaction if the wallet never go live (offline) in blockchain.info ?
Yes. Wallets are just clients. Everything is in the blockchain (which that can be viewed online).
13265  Economy / Web Wallets / Re: Paper wallet amount not yet visible in blockchain.info ? on: January 16, 2018, 06:56:17 PM
This means that the address you searched is invalid. Even if the address is empty, you can see it in any explorer.

Is your address starting with a 1 or 3? If it's not, then that's probably not an address.
13266  Bitcoin / Bitcoin Technical Support / Re: Accidently send BTC to USDT address on: January 16, 2018, 03:17:33 PM
I heard one way to do it is to find the private key and export this key to another wallet.

1. How to I find the private key of my Cryptopia USDT wallet (where I transferred BTC)
You obviously can't. This method only works if you send BTC to a wallet you control. E.g: Electrum, Bitcoin Core, etc...

They may be able to recover your USDT. But they may also charge you a fee just like they do with deposits sent without a required payment id:

Quote
Due to an influx of tickets of this nature having a significant impact on our support capacity as we continue to grow and scale to meet demand, Cryptopia is now implementing a 10% recovery fee on support tickets involving recovery of deposits made to Cryptopia where a required PaymentId/Message/etc are not correctly included in the transaction.

Keep in mind that they are literally the only ones that can help you. If they don't answer your support ticket or deny your request, your BTC is gone.

Quick edit: oops... Swapped BTC with USDT. Thx DannyHamilton
13267  Bitcoin / Wallet software / Re: Airbitz on: January 16, 2018, 02:16:07 PM
Export your private-keys[1] and keep them safe. Even if the old Airbitz stop working, you can import them in a different wallet (e.g: Electrum) and recover your funds.

13268  Bitcoin / Electrum / Re: Missing transaction on: January 16, 2018, 12:35:30 AM
I have now imported a key into Electrum walllet but the last tranaction can not be seen..
But is the wallet balance correct? Or is the value sent in your "missing" transaction missing?

I have the same proble....! Made a transfer from Binance to Electrum yesterday. Right after i installed the new Electrum 3.0.5 now i see no sign of the transaction and the address i used is not even in the list can some one please help.
Are you sure that you are opening the right wallet file? Can you try to create it again by restoring your wallet seed?
13269  Bitcoin / Electrum / Re: Low fee transaction doesn't exist on: January 15, 2018, 11:56:20 PM
When did you sent this transaction? And are the Bitcoins sent (0.07 + 0.001 fee) back to your wallet or are they missing?

Since you sent them with a low fee, the transaction could have been dropped from the mempool afer a few days unconfirmed. So the Bitcoins would be back to your wallet and they would be spendable again.

How rude to call names... Thanks for correcting me tho I really didn't know and now I improved.  
Then, next time read and search first to only answer things you know. There is no point on trying to help people (just to increase your post count) with stuff you don't know and end up spreading false informations.

Good luck in your future signature campaigns spammer!

Well that sucks, how did they make this then, it seems just like something I would do with html:
https://bitcointalk.org/index.php?topic=2710426
That's just an image with a url tag leading to the video page. If it was an embed video, you would be able to watch it in the bitcointalk page.

You can even click and go to youtube main page with it. I wish I could see the bbcode under it.
You can. Just click "Quote" at the top right part of the post.

That's the BBCode:
Code:

See? It's just an image.
13272  Economy / Service Discussion / Re: [Unofficial] Exodus Wallet | Multi-Currency | Built-in Exchange on: January 15, 2018, 05:39:41 PM
Is there a way that user chooses what fee wants to use for transactions or are fees automaticaly chosen by exodus itself?
They are choosen by Exodus and you can't customize it. If the fees are too much, you can export the keys[1], import them in a different wallet (e.g: Electrum) and make your transaction.

Just click your name right next to your post and check the URL.
Or go to your profile, click "Show the last posts of this person" and look at the URL.

You will see your ID at "u=XXXXXXX", which in you case, is: 1355399

Thank you spammer for answering incorrectly something you don't know Roll Eyes
13274  Bitcoin / Bitcoin Technical Support / Re: Fraud bitcoin and etherium transactions on: January 15, 2018, 01:19:40 AM
sir How can we avoid this kind of transactions? is their any way to determine the fraud ones?
I believe that the transaction itself isn't a fraud. If I understood correctly, he is saying that he has fallen for a fraud, thus the transaction wasn't made by him and he want's to "cancel it" just like you can do with bank transfers made by an unauthorised individual. Which is impossible with Bitcoin.

If a Bitcoin transaction gets confirmed, it's irreversible and valid. There is no "fraud transaction".
13275  Bitcoin / Electrum / Re: Electrum users must upgrade to 3.0.5 if they haven't already. on: January 15, 2018, 01:15:50 AM
What should I do to upgrade my Electrum wallet? Uninstall the current one and then install the new version or can I just install the new version while having the old version installed and it will be replaced?
I'm not sure about the other OS', but if you are using Windows, you can just install the new version over the old one.
13276  Bitcoin / Electrum / Re: How to claim BItcoin diamond and BTG?anyone help? on: January 14, 2018, 10:24:03 PM
you can use electrum diamond wallet https://www.electrumdiamond.org
PLEASE DON'T DOWNLOAD ANYTHING FROM THIS SITE.

This user is spamming his url everywhere in the forum. Just check his post history. This also makes me think that this is the new "Electrum Gold" software which was stealing private-keys some time ago.

Edit: There is no github page for this software. Just like the old fake Electrum Gold. AVOID AT ALL COSTS!
13277  Economy / Service Discussion / Re: Alternative to coinpayments.net on: January 14, 2018, 10:01:12 PM
There is this one: https://coingate.com/

I have no experiences with them, but there is a list of merchants using them at the bottom of their main page and they do several challenges at /r/bitcoin.
13278  Bitcoin / Hardware wallets / Re: Nano and Trezor addresses, should i use just one ? on: January 14, 2018, 07:23:22 PM
No i meen, why so many addresses ? Are you only using one address or are you using many addresses on you Trezor/Nano ? ( erc20 )
Privacy. Here is a TLDR:
Quote
If you use the same address each time you receive funds, it becomes easy for anyone to track your entire payment history. This method of address generation improves privacy by automatically presenting you with a new address when you’re expecting payment.

Does it not matter what address i use on the Trezor/Nano ?
It doesn't matter. You can use any address as many times as you want.

So i can just pick one address on my Trezor and only use that one ?
Yes.
13279  Alternate cryptocurrencies / Altcoin Discussion / Re: Possible hack: filesize of Electron cash wallet is different on: January 14, 2018, 05:40:21 PM
There is nothing wrong with the website. I checked in my computer and its also written "authenticty" (probably just a typo).

About the different file sizes, maybe the file corrupted while downloading? This happens with me sometimes and the file just shows as "download completed" but the size is way lower than it should be and it doesn't open without an error message.

Just make sure that you are download from this link:
https://electroncash.org/downloads/3.1.2/mac/Electron-Cash-3.1.2-macosx.dmg

And verify your files with the guide linked above.

Also download the file and use https://md5file.com/calculator to check if the SHA256 hash matches with the one in this page:

13280  Bitcoin / Hardware wallets / Re: Restore a Ledger Nano Bitcoin wallet on a Ledger Nano S on: January 14, 2018, 03:23:17 AM
This information doesn't suggest that a Nano wallet can be restored on a Nano S without the Black security card cipher. This is the KEY! Also I have repeatedly tried restoring it on a MEW and an Electrum Wallet, never works. Electrum freezes up or just crashes. Different computers, same results. If anyone has successfully restored a Nano (not S) wallet on a Nano S specifically without the black security card and then been able to retrieve their funds please share that. 3 and 1/2weeks without customer support from Ledger and counting. It did not require nor mention a security card while taking the funds, it may be my fault for not having the black card now, but ultimately it shouldn't take funds and then not send them with the exact same protocols! It's supposed to be a wallet.
I saw that you said "Nano S" before (by mistake?), which actually doesn't come with any security card. In this case, I can't really answer you. But IMO it should work without the card.

Edit: I'm reading Ledger's support guides and if I understood correctly, the security card works as your PIN. So when you can restore your wallet, you can create and associate a new security card. Read this: https://ledger.zendesk.com/hc/en-us/articles/115005211265-I-lost-my-Security-card
