Perfect, I will follow your indications for best verifying signature.

This topic brings me spontaneously to ask you another question.

Can you advise me a good bitcoin (and maybe eth Wink) paper wallet generator?  So good I can verify who is the owner and his signature, in other words a generator made up by a reliable developer.

Thanks a lot again!


Sorry, I can't advise about paper wallets. I have never used them to store coins, so I don't have enough experience of them to give good advice. I'm sure other users here will help.

Well we had 8 green weeks in a row! That's a lot!
So the chance to see some bigger correction wasn't really small when you check chart's history!
Let's see how this week will further develop. Probably a red one, which doesn't mean the end of the bull run. So no reason to panic, yet.

The week's barely begun and this dip is only less than 17%.

3 weeks ago we dipped 33% and still ended up green. It took only 9 days to hit an ATH after that big 33% dip.

We still have lots of time for this candle to turn green after today's much smaller dip.

It may still end up red, but don't count green out just yet.

I was hoping for a dip after reading elwar's experiences. He said the previous 2013 bull run ended after the price doubled in a week. This dip's slowing the bull run down and keeps us out of the doubling in a week danger zone.
2143  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: June 12, 2017, 07:57:13 PM
We'll see the bull keep going until later next week and then likely a major dump. However, we'll see 5 digits by Feb 2018 w/ a major breakout coming in 2019. That's right I said it.

This guy predicted a major dump this week. I'd call today's event a dip rather than a dump, but if it continues I'll call it a dump.

I'll be happy if the rest of his prediction is right, 5 digits by 2018, then a major breakout.
2144  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: June 12, 2017, 01:13:54 AM
This is it. My friends that have 0 knowledge or interest in bitcoin are buying BTC and ETH... The bubble, the force of bubble is in the full mode now!

Not full mode. Otherwise, we would see doublings in a week.

How long did the doublings in a week continue for in 2013? I missed the run up back then, this time round will be my first experience of a massive run up.

In 2013 it went like this.

First bubble:
Double in a month
Double in 2 weeks
Double in 1 week
Double in half a week
Up a bit then crash

Second bubble:
Double in a month
Double in 2 weeks
Double in 1 week
Up a bit then crash

Recently we doubled in a month (1250 to 2500) but then it flattened out. That's a good thing.

Thanks, that's very useful information. I tried looking at the charts, but it's not easy to see what really happened from them. Zoomed out they average out all the highs and lows.

Thanks HI-TEC99

I have followed religiously your guide posted in the link, through cleopatra I get:

generate-wallet.html.sig: Signature is valid
Signed on 2016-02-23 15:53 with unknown certificate 0x761F7D53D11591274A170B839277AD7136E1D9B6.

but, I don't have certificate of Canton Becker (the maker of bitcoin paperwallet) Grin I only have trough his website these:
PGP Public Key ... (very long as you know  Cheesy)
RSA Key ID: 36E1D9B6
Fingerprint: AB12 6777 451C 7A18 C172 3297 C525 F065 0B16 DF4B

How can I connect this certificate to him?



Ideally you should personally check in multiple places you trust that a signature really does belong to someone you trust. Often even experienced professionals skip that step and just use whatever is on a key server, but that's very risky. This quote sums up what you should do.

https://serverfault.com/questions/569911/how-to-verify-an-imported-gpg-key

Quote
A "trusted signature" is a signature from a key that you trust, either because (a) you have personally verified that it belongs to the person to whom it claims to belong, or (b) because it has been signed by a key that you trust, possibly through a series of intermediate keys.

I found a reddit post containing that fingerprint by someone with the username cantonbecker. However, I don't know Canton Becker well enough to confirm if that really is his reddit account. You will have to google some more to find something you can double check with.

https://www.reddit.com/r/GnuPG/comments/1lsuih/am_i_pgpsigning_my_bitcoin_wallet_generator/ccfzj6e/

Quote
However I don't want to put my key fingerprint in the README file itself because the whole point of signing the document is discouraging people from trusting the download itself without double-checking...

As a start, I'll take your advice and post my fingerprint info here Smiley

WTF is happening on bitfinex today? It was far higher than stamp at above $3000 earlier, and now it's lower than stamp.
2148  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: June 11, 2017, 03:39:55 PM
ATH @ BITSTAMP

And it's another weekend pump with another ATH. How long until it breaks $3000 on stamp?

I posted instructions for extracting the private keys from Bitcoin Wallet for Android at these two links. However, it's a highly technical process.

Got? Like, I was able to decrypt the file, but the twelve words did not appear, I think there are other software that does this, you need the security PIN that you have registered to protect against unwanted expenses in the wallet.

Did you open the decrypted file in notepad, or notepad++

The 12 words don't show up when you open the file using windows built in text editor. You have to use an alternative one like notepad++ which you can download here.

Read the whole of this thread and you might find the answers you are looking for. It has detailed instructions for using gpg to verify electrum

https://bitcointalk.org/index.php?topic=1836004.0

36E1D9B6 appears on this page as a subkey

http://keys.gnupg.net/pks/lookup?op=vindex&search=0xC525F0650B16DF4B

Often the primary key is used for signing, and the subkey used for encryption.

There's more information about subkeys here.

2151  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: June 10, 2017, 11:28:35 PM
OKCoin on ATH clearly above $3000.

Bitstamp on its way.

Kraken struggling due to lack of FIAT. The margin pool is empty.

Stamp is developing a big spread. It only takes 200 Bitcoins to either push it up to $2900 or down to $2800. OKCoin has a similar spread, it only takes 300 Bitcoins to either push it up to 21000 CNY or down below 20000 CNY.
2152  Bitcoin / Electrum / Re: Problem with btc, dont recev/ied on: June 10, 2017, 09:24:28 PM
The server your electrum wallet connects to might not be fully synced.

Try clicking the green circle at the bottom right of electrum, and a new window should open.



Inside the new window uncheck "select server automatically", and select a server from the list that appears. After that click the OK button and check if your coins show up in your wallet.

If it doesn't work the first time try repeating the process a few more times to make sure your wallet connected to a fully synced server.

Bitcoin address can automatically change? I feel so outdated or just not educated enough about this. This is all new to me


That feature's fairly new, it's called a hierarchical deterministic (HD) wallet. Last summer the core dev team merged HD wallet support into core's code. Instead of your wallet generating random addresses it generates a random 128 bit value and uses that to calculate 12 words. The 12 words are called your wallet's seed phrase, and you can use them to restore all the addresses your wallet will ever generate.

Your wallet can generate an almost limitless number of addresses from its seed phrase. Each time you send coins from an address it sends what's left over to a new address to store the change in. Not reusing addresses enhances your wallet's privacy. It makes it harder to figure out which addresses belong to the same wallet.

This is the announcement of the new feature on bitcoin.com.

https://news.bitcoin.com/hd-wallet-support-finally-coming-bitcoin-core/

Quote
HD wallets are an important use-case for the bitcoin ecosystem. This is because deterministic wallets don’t reuse bitcoin addresses, which helps with user privacy.

There's an explanation of HD wallets here.

Someone seems to dislike the thought of $2900 in Western exchanges. China is constitently pushing towards $3k.

The question is how BTC will behave in the epic bust that many are expecting imminently, because even gold crashed in 2008.
Staying somewhat liquid could be advisable.

That's Bitcoin's use case. When banks start going bankrupt Bitcoin's going to get pumped higher than any of us can imagine. During the next wave of bank bankruptcies they will be bailing themselves out with our money taken from our bank accounts. Even the people that own the banks will be putting their money into Bitcoin rather than bank accounts that are guaranteed a 50% haircut.
2155  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Core client extremely slow and unresponsive when synchronizing on: June 10, 2017, 03:18:06 PM
Okay, great! I followed your instructions and was able to load it on to electrum.

I do see my past history from back in 2014, but my balance remains zero.
Does it need time to update?

Search for the addresses you think should contain coins at this block explorer website If both your wallet and that site says an address is empty then it's probably empty.

https://blockchain.info/

If you use that site to search for every address that shows in your Bitcoin Core client you might find one that contains coins. Maybe you forgot which addresses you sent coins to after all this time.
2156  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Core client extremely slow and unresponsive when synchronizing on: June 10, 2017, 09:16:57 AM
Thanks for the fee info. I understand now.

However, I'm still having problems with syncing. Is there a "light" wallet that uses "wallet.dat"?


Not that I'm aware of. However you can install the electrum light wallet, then use the instructions in the quote to export your private keys from your Bitcoin Core client and import them into electrum.



Click file, then receiving addresses. Find the address you sent coins to in the window that opens, right click it, and select copy address. Close the addresses window.

Click help, then debug window.

In the debug window that opens click console.

In the text box at the bottom of the window type

dumpprivkey yourAddress

where yourAddress is the address you sent coins to and copied earlier.

Press your enter key.

The private key for that address should appear in the console window. Copy it.

This is an example private key.

L48toSntMVhC2az4KAQCWscrQGfPbT55yCgzM5cmx9Ao69pTdwrq

Download and install electrum.

https://electrum.org/#download

Import your private key into it using these instructions.

http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clients

Afterwards your coins should be spendable.

Disclaimer: Don't blame me if it steals your coins, I don't know how reliable the author is.

Ya I wasn't sure if some normal wallet could do this with some fancy maneuvers. I guess not and I don't want to have to trust someone else's coding skills. Thanks for the help though!

Here you go: https://github.com/aeternity/wiki/wiki/How-to-sign-a-message-with-a-private-key%3F

I've contributed one of these methods...

Tell me if you need any help.

- Make offline copy of the HTML.
- Copy on USB stick to offline computer
- Run the website offline
- Sign it via HTML / JavaScript
- Put the signature on USB stick / write it down

PROFIT / DONE

Click +1 if it helps you Smiley

I'll check it out and see if it requires any trust. Thanks.

There's another offline webpage that can sign messages for you at this link. However any such webpage shouldn't be trusted when online. I wouldn't consider using it unless it was run in an offline isolated environment.

https://brainwalletx.github.io/#sign

That webpage is capable of creating five different message signature types including multibit's and armory's.

how to import private keys from multibit classic into the latest electrum at these links.

This is not the problem, you can import it, but electrum won't let u use it, it only let u swipe it to HD wallet :/

You can use it without swiping it. It gives you the choice of either swiping or just importing a private key and using it. I tested it and it works OK.
2159  Bitcoin / Bitcoin Technical Support / Re: Vanity address friendly clients software/mobile/online on: June 10, 2017, 12:03:43 AM
I love vanity addesses since years but lately i have more and more problem finding client, that  actually accepts vanity addresses (importing private key).
Now is HD wallet era, so what wallets i can  choose from except old ones like multibit classic and old electrum? What Vanity address friendly clients are there (software/mobile/online)?



There are instructions explaining how to import private keys from multibit classic into the latest electrum at these links.

https://bitcointalk.org/index.php?topic=1959005.msg19463119#msg19463119

http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clients

Although the latest electrum is HD by default it's still capable of importing private keys.
2160  Bitcoin / Bitcoin Technical Support / Re: How to sign a message from a paper wallet without importing your private key? on: June 09, 2017, 08:21:11 PM
Download this webpage and run it inside a browser from an offline live CD.

https://coinb.in/

Go to the sign section, input your private key and message into the text boxes and click the submit button.

https://coinb.in/#sign

Don't ever put your private key into an online version of it.

I'll give it a shot and see if it's simple enough for me. Their website seems to say it's simple enough so let's hope they're right Wink

Sorry, I made a mistake. You can't sign a message with that page, you can only sign a transaction.

Sleep deprivation got the better of me. This is the webpage that signs messages. Don't ever use it unless it's in an offline isolated environment like a live CD (or preferably a virtual machine).

Disclaimer: Don't blame me if it steals your coins, I don't know how reliable the author is.


*snip*

4. Now I have created a foolproof bitcoin signing tool which you can find here: https://ordinarydude.github.io/offline-bitcoin-signer/

5. Use the private key and the messages to obtain your signature.

Disclaimer: Use at own risk, the sources for the offline signing tool can be found here: https://github.com/OrdinaryDude/offline-bitcoin-signer
The paranoids download the code and sign on an offline machine!



Screenshots of this process:
