Topic: [Guide] Use Bitcointalk (more) privately (Read 693 times)

You're missing the point: I'm much less worried about my privacy on KnittingParadise.com than I am on Bitcointalk. I'm pretty sure a knitting granny doesn't do $5 wrench attacks to steel my wool.
I left you neutral feedback from LoyceMobile (not on DT) after your plagiarism in January. I've replaced it by the same feedback from this account.

But it is never late to learn something new. The information shared in this thread may be useful while using other sites on internet in future.

For many of them it is enough and it does not raise any problems for them. It is common for other services like normal banking as well. Some bad instances may occur to some users but for majority, life will complete peacefully even after not following the precautions in this thread.

According to what can be read on the official site TOR can be used in China, but requires some additional actions by users. It would be interesting to know how many people in China use TOR or VPN, or how many dare to go against the regime, given the penalties in that country. I assume that every ISP can see what the user is doing, and therefore I do not doubt that the Chinese ISPs in its fanatical surveillance monitors these activities as well.

Thank you for this guide, certainly very useful especially in countries where there is repression.
It is not only useful for using bitcointalk but in general where some things are not allowed.
But does TOR for example work in China? I've always wondered about this.

i have to agree with this statement. it's difficult to choose both coz eventually you'll have to choose one and proceed with that.

i do prefer using my opera rather than tor and changing browsers is not that convenient for me, i have tried tor once and we are not compatible so i just choose a browser which is convenient for me.

Why Opera and not another browser? For example, Firefox. Will Opera be able to provide a level of privacy at least close to TOR, or have you chosen what is convenient and familiar to you without giving a damn about privacy?


But other browsers also need to be configured before initial use, and not use the default settings.

Although, you can’t argue here: most users will always choose convenience and practicality over privacy.

But ProtonVPN's obfuscated servers work in Russia, Iran and Egypt.
China is a very individual case, sometimes some VPNs work in China, sometimes - not. At the moment, Astrill VPN is very popular in online Chinese communities. Chinese usually use Shadowsocks, V2Ray, Xray, Trojan, VLESS, or gRPC to bypass Great Firewall of China.
By the way it's a good idea to add in my thread VPNs or methods that work in China to bypass their internet cencorship.

I use an app called "TOR Browser", because the onion browser does not reliably work for me (or should I say not at all)!

It's good if you don't mind the occasional nagging to use the built-in VPN - honestly, I never use it, as a Proton Visionary subscriber.


ProtonVPN servers can also be exported as OpenVPN profiles. None will work in eg. China, unfortunately.

Why? We all have models for passwords, even if it is the simple fact of using "software" to create passwords.

Also, the main passwords should be kept in a safe place, in case something goes wrong.

I don't think your are the only guy in bitcointalk forum from same country, but they could also send that same t-shirt to any neighboring country PO Box of mysterious person, since there are no real borders in EU  

LoL, but you brain is also a system, and when it breaks that means you don't have any backups.
You can do whatever you want, but most cases of people losing passwords and bitcoin keys is when they tried to act smart creating their own ''systems''.

Sorry but I have to say that you are making perfect recipe for disaster with your unique password model, whatever that is.

Having strong passwords is good, but 2FA is better because no password is strong enough not to be cracked with a quality config and combolist. A lot of accounts could get cracked using good checkers, so when that happens even if the cracker got the username and password they can't access the account if s/he don't pass through the 2FA requirements. For a forum like this having the question and answer feature set up is also recommended, to enable easy account recovery. Hence, since the forum is not a target to crackers, its nothing to worry about, since the forum account sales market is falling on daily basis. Though, your thread is very excellent, as we are meant to be security conscious online and keeping things private is important.

I also have a question, what happens to a person that doesn't have a picture anywhere online, how can he be traced? if their privacy is leaked that is they don't use VPN, Tor or all the tools you just mentioned, between the forum encourage users not to attach their real faces on the site.

Maybe I didn't explain it well. And what I did was just an example. Furthermore, the world does not only speak in English.
The idea I mean is that it doesn't necessarily have to be random in human eyes, but rather random in machine eyes.

This is a little bit what I want to say:

Maybe my English is not the best and I can't explain it in the best way.
I apologize.




I also wouldn't trust passwords created by a password system, because if a system can create them, it can also crack them.

Either way, you can rest assured that I have my own password model, different in many aspects from those discussed here, which, as you may understand, I will not share here.

Like I said, I can remember a few passwords. But I can't remember hundreds of them, and most of them I don't need very often. If I'd try to remember them all, I'd either have weak passwords, of lose access all the time.

I always type with my eyes closed

Definitely it is less alarming. VPN is used by people to bypass restrictions that mostly include access to some games, game servers, netflix/hulu and so on. A lot of people use vpn with servers in Turkey to get cheap access to digital services.
Even if you want to hide your VPN usage from ISP, you can use VPN with obfuscated servers like ProtonVPN with Stealth mode or setup OpenVPN with obfsproxy.

By the way, if you use Tor bridges without VPN, node owner may know your IP address and in case nodes get compromised, others will know it too.

That's true but I always wonder what kind of prediction can someone find, for example, in this password: 'railWayZDanieAccCausticCornUebung'. I'll explain: Railway is railway, ZD is Russian word, short version of здapoвa (Hello), Zdanie is also Russian word здaниe and means building, Acc is a short version of Account, Caustic is caustic, for example caustic soda, Corn is a corn and Uebung is a German word Übung that means practice.
I agree that humans are very bad at randomness but I'm curious why these combination of words doesn't sound or look random.

No, that's wrong. These are all regular English words found in every wordlist and cracked in minutes.
https://en.wikipedia.org/wiki/Dictionary_attack

No, I said the opposite. Letter-by-letter bruteforcing is probably dead for well over a decade now.
https://ieeexplore.ieee.org/document/4799025

That's entirely backwards. The second option is orders of magnitude easier to crack, since it is just 7 words and a number. As the sentence even makes semantic sense, some crackers should have an even easier time guessing that password.
Meanwhile the first option consists of 15 random characters, so wordlist-based attacks don't work and one would have to default back to the much slower / 'legacy' byte-by-byte bruteforcing approach.

Sure; thanks for the suggestion. I will do such a guide in the future. But in essence, you just connect to https://boltz.exchange/ via Tor (you will be redirected to their Tor site), enter the amount you want to send to your Lightning wallet (such as Core Lightning) and send the amount shown on screen through a regular on-chain transaction.

No, he won't.

That is wrong. By definition, a sentence has less entropy since it does not consist of random letters.

There is not much to discuss; it is mathematically proven that truly randomly generated passwords are much stronger than real words and sentences. We don't need to mix a strong system with a weaker system, either, that only reduces security.
My mate, I honestly suggest you go and change all of your passwords, now..

It depends: if you're comparing one random character to a word, the word is harder to find. But if you compare 4 random characters to a 4-letter word, the word is easier to brute-force (by using a dictionary attack).

Both isn't ideal, but VPNs are often used to connect to a company network too. Or for streaming.

"I'd like to give the t-shirt I won to a Newbie who lives in the same country as me"....

What makes you think they're equally strong? If the first one is generated randomly, it's much stronger. If you want to use words as a password, at least generate them randomly. Kinda like Electrum does it.

You should look up the words "dictionary attack"

The phrase indicated was just an example, I do not recommend that it be used, much less that it be so logical.

The point I wanted to emphasize is that for a hacker who steals hundreds of passwords, he will use automatic systems that will try to match the victim's password letter by letter. The probability of him hitting random letters is greater than a sentence.

I am not recommending this or any other type of password here. Just to point out that both types of passwords can be safe if used correctly.

Perhaps a mix of the two options could be something interesting to explore.

Guess what, i have made a username with my real name. Never thought about the privacy back then when i created this bitcointalk account, but now its too late.

Generally, the IPs are logged for last 30 days. So if we opt for this limited IP retention, won't they be logged at all ?

It will be great if anyone can tell the procedure of doing this with a lighting wallet. A step by step procedure or guide may be really helpful along with links to site / wallets etc. Usually how much fee is involved in this process ?

The second one looks pseu-do strong but in fact it is not. It is more vulnerable to bruteforce process because you don't know what are bad guys who intend to steal your passwords.

If it is people around you and know you love cat and some other information about your cat, he will put words like "cat" "2" "old" into inputs of brute force and make it becomes more easily to bruteforce your passwords.

If a person has his habit to create password like this, possibly he will have other passwords like
My3YearOldCatLikesYoWalk
My4YearOldCatLikesYoWalk
My2YearOldCatLikesFish

https://www.youtube.com/watch?v=rMtW8vIHHek

But it's not the special characters that make the difference in this example password. It's the phrase. Systems typically match words, but not phrases.
The system can combine "water" "salt" "sugar". But combining as a phrase "water" "with" "salt" "and" "sugar" is more unlikely.
Of course, this is just an example, and I'm not saying it's invalid, just that it's less likely to happen.

As you said rightly, the systems normally check letter by letter. Therefore, it is more likely to pick up a combination of random letters than a sentence that is understood by a human.

Which do you think is easier for an automatic system to find:
"1McY1aGwc8jvFtA."
or
"My2YearOldCatLikesYoWalk."

Both are equally strong, but the second option is much more difficult to be recognized by an automatic system than the first.

I assume that various AI programs are already mass collecting information for anything related with specific IP addresses, names, usernames and style of writing.
Anyone that is using modern smartphone is in much worse situation for privacy and Tor on Android or iOS is not as good as on regular computers, plus there are many other things smartphones record about users (like we saw in recent CM incident).
My main suggestion is to stop using smartphones and switch back to old mobile phones if you care about privacy, but if that is to drastic than use de-googled phone (GrapeheneOS is interesting).

This is happening for almost all websites and forums, so it's even worse if someone used same real IP address on multiple websites.
Maybe you can add suggestion for people to use temp emails, or services that allow creation of alias and additional email addresses.
It would be perfect to self host your own email address, as we already saw how Proton mail and other ''private'' services can give all information to authorities.

You could eaisly use secondary accounts for purchasing stuff from forum... and I don't mean LeyoceV Mobile  , but some random newbie account.

Is it less alarming to show your ISP that you are using a VPN?

Yes, I highly recommend doing these things, I consider them standard procedure.

That is unfortunately completely wrong. Your example password is extremely easy to crack. Password crackers nowadays don't brute-force letter by letter anymore, but are based on wordlists. They also take into consideration that people like to append special characters and numbers to the beginning or the end of the password. Humans are way too predictable to be trusted to generate randomness; this is a scientifically proven fact.

I was hinting at reasons privacy may be of interest to you, after all. Especially in relation to your forum profile. It is possible and maybe desirable to e.g. have and use a KYC-ed account on an exchange (although I highly advise against it) and have a completely separate online identity with no ties to that account. It is not too hard to accomplish, as I outlined in the OP.

It is not recommended to memorize all your passwords because they should be unique, complex, and random for better security. Instead, consider using a password manager to securely store and manage your passwords.

I understand the risk of providing KYC documents to centralized platforms but it's somehow unavoidable at all circumstances for instance I used to trade a lot so I don't have any other option than doing KYC verification then only I get the higher trading limits, and for casino it's almost become mandatory on every crypto casino so it's you decision whether you want to use their platform or not but I have done KYC on Roobet since I am using their service and also I can't advertise without knowing anything about the platform.

I think this was one of the best sentences I've read about privacy!
Sometimes people focus a lot on privacy today, but forget what they did 10 years ago, which ends up destroying that supposed privacy.

I'm in a similar situation with you. Therefore, today I only take the measures that I think are necessary for privacy, for the level of privacy that I still manage to maintain. For the rest, I just have to be attentive and take the necessary care not to fall into schemes that could harm me.




I may disagree with some of the points mentioned, but I think the use of real words, depending on how they are used, is a not bad model.
A machine finds random letters faster than real words. Logically it cannot be just a word or two. But, a sentence, with three or four words, can be very difficult to crack as a password.

In reality it all depends on how you build your password.
Random letters and numbers can be as easy to break as a few words together.

The suggestion I always give is to build passwords that you can memorize, but at the same time are complex.

"Waterwithsaltandsugar!1" it could be someone's password, which will be very difficult to be cracked.
Well... now it's not... it's better that no one uses it.  

For exactly this reason, I've refused physical prizes that I was offered, and never bought collectibles. It's unfortunate, but each time a "Trusted member" turns out to be a scammer I'm very happy I kept this part of my privacy.

It depends on who you're hiding from. I'm not hiding from taxes, and I'm not hiding from law enforcement. But if you are, you should indeed not use any centralized service that requires your real data.

If we wanted to go all the way, we would also have to delete the metadatas included in the photos of the narketplace's ads posted, not use an address that has been in contact with a CEX for a signature campaign (and I imagine that this is quite often the case).

In absolute terms, you should not buy or sell anything on the forum in order to protect your privacy. You don't know who you are sending your address to.

In my opinion, being careful on the forum is not especially necessary (even if I actively support the principle you defend in this post), because I am sure that a lot of members can be already linked to a deposit/withdrawal made from a CEX via an address they posted here. Even with all the effort, the CEX will cooperate with law enforcement if necessary, and the efforts to protect themselves here will have been for nothing.

I'm nearly almost relatively 86.72% convinced that if law enforcement needed to track down a member of bitcointalk, they wouldn't need a trail of pizza-sized breadcrumbs to do it (except for Satoshi, apparently).  Nor does Chipmixer even stand out in my mind as anything special in terms of crypto debacles aside from the fact that I and many others didn't know what was *apparently* happening, or what would happen.

Part of me thinks this has become such a big deal on the forum because their signature campaign was extremely selective and had a lot of not only excellent posters but trusted members as well, and they like to see them get a sort-of comeuppance.  Like Schadenfreude, you know?

Or maybe that's me just being my misanthropic self again.  Nasty mindset to get out of, let me tell you.

I know that many people do lose their accounts but here we talk about improved security.
If a service uses SMS for recovery, that means that you have to leak your mobile number. Yeah, it doesn't need to be actually your phone number but I would avoid it. And I don't understand how can someone gain access to your phone that way? What does SMS recovery option has to do with your phone access?

If you use bitcoin address without transactions just for signing a message, okay but if you use it for transactions, I don't think your info is safe.

That's the type of password everyone should be using. It's your choice if you try to remember them or not but believe me, if you try, that's not difficult to remember. Type that hard password frequently for months, for a year and then you'll realize that you have memorized it so well that you can type it with your eyes closed.

Is it better idea to show your ISP that you are using Tor? Don't you think it's alarming? You may use tor just for your privacy but a lot of people use it for illegal activities, your ISP doesn't care what your actual purpose is, your are under their radar.

Forgot about Orbot that is useful if you need Tor for other things than only web browsing.

Dumb question

Anyone know who to use two features on mobile
New identity: Ctrl+Shift+U
New Tor circuit for this site: Ctrl+Shift_L
The second one is important because when you use Tor, sometimes it sucks and if you close it, you lose your post content.

Another common mistake is using a few different passwords, and not remembering which one is used where. So when trying to get access, those people try all passwords they know  until one of them works, without realizing they've just compromised them all.

You must be really biased, otherwise I see no way how you can misinterpret my reference to recent events and the topic as a whole so badly.

It's also sad to see forum members buy into this 'privacy = criminal' misinformation campaign. Privacy should be a fundamental human right for everyone. It has nothing to do with criminal activity.. sigh. Next time you are going to tell me Bitcoin is only for criminals, because it is pseudonymous? We should tie our real identities to our Bitcoin address if we have nothing to hide? Why do you use new addresses for different payments, are you a criminal?

The Privacy Culture Manifesto

This is a common fallacy. Limiting the amount of data you leak to the world is always good for your privacy; there is no black-or-white, no 'private' and 'unprivate'. The more you share, the lower your privacy; it is a gradient, a spectrum.

Ask the millions of people resetting passwords every day.. This is also off-topic. Of course you don't need account recovery if you properly stored your password, I know. But things can go south (house burnt down, password manager hacked, whatever) and you may still have access to your Bitcoin keys. The staked address is just one extra layer of security.

Obviously don't use an address tied to your identity. You do know you can create 'sub-wallets' under a certain seed by using derivation paths and passphrases, for instance.

A VPN is a central point of failure potential spying, so that's why I do not blanketly recommend  using VPNs. They have their use cases, but may not be a good idea for everyone.

Thanks, adding this to OP!

I agree with Loyce. You should have a different password for each account and they should look like that (no regular words, no dates etc.), absolutely. As people tend to have dozens to hundreds of accounts, if you can memorize all of your passwords, they are either:

• Not distinct enough (i.e. not a fresh one per account)
• Not independent enough (e.g. you have a 'master password' with numbers at the end or something like that)
• Not random enough (e.g. you use real words)

The forum is not only central, but:


You can read more in the privacy page https://bitcointalk.org/privacy.php

In short, all the data that you share here, I assume that everyone knows it, because the IP addresses, your private messages, etc. can all be reviewed by the administrators.
Using a centralized platform wallet, social media accounts, keeping cookies, javascript enable etc. are all things that help identify you.

Tor browser can do that too, but it ticks "Always use private browsing mode" by default.

I'm not losing my account, but many people do. And when it happens, for instance because someone gains access and changes the password, it's good to have a recovery option. That's one of the reasons I staked an address.
Note that "recovery options" are often a risk factor on their own. If a service uses SMS for recovery, gaining access to your phone is enough to gain access to that service. That's why I prefer not to enable recovery options, although a signed Bitcoin message is safe enough for me. If anyone gets access to my wallet, they have access to my forum account already.

Doesn't that break rule number one?
