301  Alternate cryptocurrencies / Altcoin Discussion / Re: How anonymous are Dash transactions? on: August 15, 2017, 03:34:22 PM
We don't need Dash to be anonymous.

1- Create an encrypted BTC wallet on your PC, connected via TOR

2- Buy BTC on Bitstamp with Fiat

3- Send BTC to your local wallet

4- Save the encrypted wallet.dat in cold storage or online drive, just to have a backup

Now, adversaries may think you sent coins to yourself , so that shady local BTC address probably is yours.

BUT, when they knock at your door they will find just encrypted data and you are not going to give them the password.
So they don't have the proof that BTC address is yours, right ?

You can pretend that someone hacked your Bitstamp account and robbed your coins

P.S. Alternatively we can use I2P instead of TOR, but i am not sure it will be more secure, i don't know the differences and implications from a privacy standpoint
302  Alternate cryptocurrencies / Mining (Altcoins) / Why is ETH mining more profitable on AMD cards? on: August 14, 2017, 02:55:12 PM
I am curious to know the technical answer to this question: why is AMD stronger  than NVIDIA on calculating Ethash algorithm?

Is there any relevant GPU computing core difference that made this possible?

Or is it just a matter of OpenCL device drivers ?
Maybe the way NVIDIA implemented their drivers made it inefficient to calculate ETH algorithm so that AMD is stronger on ETH

Don't be afraid of being too technical while answering, i wanna dig as low-level as possible on this topic

No, not BitShares. Bitsquare: https://twitter.com/bitsquare

It's an open-source desktop app that allows you to trade without third party risk. You can't get anywhere near the liquidity and order matching capabilities of centralized exchanges with it, though. I just googled them and they just re-branded to "Bisq" within the last month, apparently.

Sadly nobody is using it.

Perhaps because it does not support Fiat ? Or because people perceives it as not safe
304  Bitcoin / Electrum / Re: [WARNING] be careful about Electron Cash or the fork of Electrum for BCC on: August 14, 2017, 12:58:33 AM
No offense but with both Trezor and Ledger Nano S both supporting BCH now I think you have to be nuts to use Electron Cash. If you can't afford a hardware wallet you probably should not be in the game. At minimum just run your own Bitcoin ABC client.

With Trezor or Ledger, can you claim your  BCC  with your seed as you do with Electron Cash?
305  Bitcoin / Bitcoin Technical Support / Re: Exporting all private keys with Bitcoin Core and upload them to cloud on: August 13, 2017, 12:41:30 AM
Suppose you have a business and you have a wallet with thousands of addresses.
This may happen because you may want to generate a unique new address for each payment you receive, and that could lead to creating hundreds of new addresses per month.

Is it sustainable for a wallet to have hundreds/thousands of addresses?
Or should you "split" things to multiple wallets/computers ?

Besides that, you may want to create a backup of your 8546 private keys in a few clicks everyday (for example).

I would prefer to export all my private keys to a file encrypted with a password that i enter, is it possible with Bitcoin Core in just a single step? (not having to do the same procedure for every single key).

Then i could upload this encrypted file in a decentralized blockchain-based file storage like SIA or StorJ : http://sia.tech/
https://bitcoinmagazine.com/articles/storj-vs-dropbox-decentralized-storage-future-1408177107/
Being that cloud storage  decentralized, you have the guarantee that your files will  always be available for download, never blocked or removed.

What do you think ? What blockchain storage do you suggest for that?

You can encrypt your wallet.dat file directly from the core.
Using this, you can then upload that wallet.dat file to the cloud and have all of your private keys encrypted.

When encrypting the wallet.dat file:
• Use a secure password with lowercase, UPPERCASE, and numbers at the minimum.
• Use at least 15 characters.

Thanks.

You think a cloud storage blockchain like SIA or Filecoin is safe ?
https://filecoin.io/

I want to be sure my file will always be there for me to download,
so it is not advisable to use centralized services like GDrive, Dropbox, etc. to backup a wallet

That's a related but different topic though
306  Bitcoin / Bitcoin Technical Support / Re: Exporting all private keys with Bitcoin Core and upload them to cloud on: August 12, 2017, 07:34:05 PM
Have you been using HD keys? Are they all part of the same wallet? If you just have your master seed key you're all set. Any address can be derived from it (which is the whole idea with HD wallets). If you have all individual addresses you'll need to back up every private key.

I have a new version of Bitcoin Core, downloaded 2 weeks ago, and it is still synchronizing ( i am opening it just a few hours/day ).

After finished i can tell you if i have HD seed, but i think so since it's a new wallet, right?

Anyway this HD stuff seems magic to me.
How can a single little "seed phrase" can restore  for example all my 15,845 addresses? ?
Wow
307  Bitcoin / Bitcoin Technical Support / Re: help with importing pvt keys please on: August 12, 2017, 07:23:47 PM
So if you have 1548 private keys in a text file, one per each line, you can import this file with Electrum in one go.
Provided that each line has a WIF key and not other format

Is it possible with Bitcoin Core as well?

How about exporting? I want to export all of my keys in one go possibly in one file with one line per key.
Possibly WIF keys but that's not important, i may run a script that converts them to WIF

309  Economy / Exchanges / Re: BTC-e hacked ?? on: August 12, 2017, 01:31:27 PM
there are more and more real investors moving some funds from fiat into crypto as a method of preserving wealth. The next phase will be people asking for their wages in crypto

That's what i hope for.. i am tired of wasting away the 30-40% of my wage in fucking taxes. Am i working like a donkey to give money to thieves ?

A wage in crypto has no taxes, and that can boost our wage by at least 25-30%

Keep only in mind that this requires also anonimity
BTC is not equal to anonimity
TOR+BTC is
310  Economy / Exchanges / Re: BTC-e account speculation thread on: August 10, 2017, 03:29:24 PM
Interesting thread. I completely forgot about the possibility of a BTC-e account market emerging, but it looks like that's going to happen one way or another.

Once the first withdrawals have been confirmed my guess would 70-80% of the 55% that can be withdrawn instantly + maybe 20% for the BTE tokens. Which would put BTC-e accounts at 47.5% - 53.0% of their original paper value. Of course the main assessments a prospect buyer would need to make is a) What are the legal risks of taking funds from a possibly illegal source and b) What are the chances of BTC-e being able to fullfill the remaining 45% within the foreseeable future.

Either way, good luck everyone. I was lucky enough to withdraw what little I had kept on BTC-e a couple of months ago.

You forgot ...

c) What are the chances that the actual balances in the account you bought are what you expect?
I sell you my account loaded with 3BTC , for just 0.5 BTC, a great deal uh? ... but when you login you realize that balance is 0

@A.Zimmerer
Don't do it = Don't get your coins

As far as i understood they require you to send your docs before you can withdraw. FIAT or coins doesn't matter

If you have only coins you can try sending a fake ID i guess, but how can you get a fake ID??

Nope, we should convince BTC-E to do the right thing.
Hand over our coins and token without verification!

Sending fakeID is no solution Lionel. So I will have to become criminal
to get my coins + tokens from criminal ? Nonsens...

If they know it's a fake ID, it means they already knew who you are.
Verification would not make sense then.

If you give a fake ID there is no way they can tell it's fake.

The problem is:  how can we get a fakeID ??
312  Alternate cryptocurrencies / Mining (Altcoins) / Nicehash miner: forcing to mine the currency i want on: August 10, 2017, 03:08:35 PM
Hi,
i am using NiceHash miner but
i want to disable auto-switching of the currency and telling it to mine a specific coin that i want.

How to do that?

Also, will NiceHash automatically run the best mining software for that currency ?

Value is 0

How can you prove you have 5 figures there?

The same applies to everybody

Well, if the site relaunches (or balances are transferred to a "new" re-branded exchange), accounts can be logged into and thus escrowed. The balances can be verified by the escrow, who can transmit login credentials to the buyer.

Oh... could work if the escrow is not going to rob you.

People who just have crypto and no FIAT may better send just a fake ID and withdraw themselves

Dont listen to mayax he stated many times he is happy we lost money.

He is the guy who goes to terminal ill children and say that its their own fault that they are dying.

I am the one who is saying that the era for unregulated exchangers is gone. if you have a tinny brain, you will realize that the anonymous shit you advertise is pure sci-fi.

This is only partly true. On one hand, bitcoin and cryptocurrencies in general are attaining mainstream acceptance, so regulation is becoming the norm and dark markets and money laundering havens may be shut down. On the other hand, privacy-enhancing technology is improving everyday. Currencies like Monero seem to largely aid anonymity (time will tell as experts continue to try break the technology).

Tumblebit could be be a game-changer for Bitcoin fungibility. Between heightened fungibility and decentralized crypto exchanges, the future for the unregulated exchange of cryptocurrencies does not look completely dark.

First of all i still don't see the point of creating all of these anonimity tools to be used together with Bitcoin when Tor already exist that can do it, and  I2P as well if i'm not wrong ( see https://bitcointalk.org/index.php?topic=151181.0, and https://github.com/VirtualDestructor/bitcoin-qt-i2p ).
That Tumblebit was not necessary at this point, right?

Monero , Dash and other crypto that implement built-in anonimity make more sense because at least they avoid the need to use external tools on top of the wallet client, and this makes those crypto usable by non-technical people that want to be abonymous. This is a great advantage over Tumblebit or Tor etc. which are more complicated for sure.

About all of these exchange incidents... i think that people must quit with this trading mania and start realizing that the true power of crypto is that you can get an anonymous job paid anonymously so that you avoid taxes and you earn more.

Everyone would get a wage at least 25-30% higher by having an anonymous job payed in BTC and the power of the Elites will end finally.
And employers as well can benefit because otherwise they are subject to overwhelming taxes if they live in a Western country.

I don't understand why once upon a time all of these trading and betting maniacs did not exist despite the average citizen was wealthier than now.
Now you are all poor and you like risking your bucks like they're nuts by playing these risky games because you hope to get rich and escape from the poverty that your Gov caused you through taxes.

So everybody  let's start working anonymously and poverty will not be your problem anymore.
Quit trading... trust me

318  Bitcoin / Electrum / Re: Electrum server discussion thread on: August 04, 2017, 05:45:37 PM
You should be able to use the Windows executable that you can download from https://electrum.org/#download.

I have it for Windows but it doesn't have the daemon AFAIK, while Bitcoin Core has the daemon on Windows as well.

I need to call the wallet via JSON-RPC from my scripts, so i need the daemon
319  Bitcoin / Electrum / Re: Electrum server discussion thread on: August 03, 2017, 11:00:31 PM
Instructions on setting the RPC port can be found here - http://docs.electrum.org/en/latest/merchant.html

Electrum itself is a python application and the version you linked to is for Ubuntu (not Windows).

Thanks.

Since it's python it should be portable like java, so i wonder why it's just for Linux.

Anyway seems like bitcoind is much easier to get working on Windows at this point..
320  Bitcoin / Electrum / Re: Electrum server discussion thread on: August 03, 2017, 08:55:35 PM

Thanks ; )

How can i run it in daemon mode on port 7777 on Windows?

Maybe i need to use the Python version of Electrum ?
