Wall Observer BTC/USD - Bitcoin price movement tracking & discussion

[OutOfMemory]

Good day 

So i see BTC at $55k, out of shallow waters, where the bears satisfy their thirst.
I'd like to see the price a lil higher today, above $55.5k, just to make sure we left the dump behind.
Expecting fights at well known levels like $58, $60k and $62k, so $70k by may (which rhymes beautifully) may become very real.

Found another Bitcoin price prediction chart today

[philipma1957]

So the 70k heslo in 1 month guess is back on the map....

70k by may 1 for sure

quoted

my lowest buy was like 48.3k this dip, a buy i had set a tick above 47k never went off though. kinda a bummer.

I got in at  4 price points

51,037 Apr 22
49,853 Apr 23
49,322 Apr 24
48,249 Apr 25

@ OutOfMemory 70k by May is a very nice rhyme




My first post on 70k by may 1 below:

Another 60k+ so we are coiling to go past 70k asap.  By May 1 for sure. that would be 2 weeks for today.

[Torque]

Increasing base-layer capacity to, what, maybe 30–40 tps tops would be a sick joke at a cost that would surprise people.  It would not solve any problems, and it would create many.  We need technologies supporting tens of thousands of TPS or more; a doubling (or whatever) of the current blocksize is insufficient by orders of magnitude, too much and not enough all at once.

Do we though? I keep seeing people, big blockers and some OG's alike, banging on this proverbial drum, year after year after year, as if it such a dire, imminent need.

But if most bitcoiners see Bitcoin as 99% SOV and and 1% or less as a transaction medium, then no, it's not. And we don't. The current TPS limit will continue to serve just fine.

And Gresham's Law will continue to prove that out.

There is a reason why the acronym "HODL" is so identified with Bitcoin, but certainly not with fiat.

I bought in the first dip between 53,9 and 54,4
The last dip I got a bunch more between 47,9 and 48,1

I’m back to about even on my first drippings now and up on the 2nd..

Figure I’ll be pretty happy with all of it once we are back over 60..
That money was kinda supposed to be for something else, like responsible adulting, but I couldn’t resist..

Reminder: don't trust password managers...

This is bad security advice.  You hereby win the award for the worst security advice that I have yet seen in 2021; that is quite an achievement, given the popularity of truly horrid security advice by total idiots.  STOP GIVING BAD ADVICE.

One of the most important actions that users can take to secure their online accounts is to use a password manager.  Use a password manager.  Use a password manager.

Backdoored password manager stole data

As many as 29,000 users of the Passwordstate password manager downloaded a malicious update that extracted data from the app and sent it to an attacker-controlled server. Bad actors compromised its upgrade mechanism and used it to install a malicious file on user computers.

Will you next so fallaciously abuse particularized examples of insecure or malicious wallets, fake Electrum downloads, etc. as generalized evidence that Bitcoin is insecure?  “Reminder: don’t trust Bitcoin.  Bitcoin is hacked.  Bitcoin was hacked through its update system.”  

Note:  Some people lost their life savings due to the above-referenced hack.  Solution:  Check PGP signatures to verify downloads!

Stop the ill-informed FUD.  See the PTIO list that I advised SwayStar123 to use, and use a password manager so that you can safely use long random passwords that are different for every site (= security), without accidentally losing your passwords and locking yourself out of everything (= availability):

Did you find out why your account was hacked in the first place ? Did you used an easy password or you told your password to any friend etc ?

Keep a strong password and hopefully no one will be able to hack your account.

reused password

Here is a selection (onion) of secure password managers for you.  Bitwarden may be easiest, if you are accustomed to being dependent on cloud stuff like all of the cool kids who obdurately refuse to end sentences with periods.  Bonus:  It is open-source; and if you want, you can run your own server instead of depending on theirs!

If you have reused passwords, then you should register at have I been pwned? (not a typo).  What you thus discover should properly scare you into never, ever reusing passwords again.

<blink>:emoji: Never reuse passwords! :emoji: :emoji: :emoji:</blink>

P.S., protip for blackhats:  Phil_S probably either reuses passwords, or uses weak passwords, or both.  This can be inferred, because without a password manager, it is humanly impossible to use a strong, unique password for each and every site.  Please go find some incompetently run site that Phil_S also uses, steal its password database, use Hashcat to recover his password, and then use the Phil_S account to post porn in the Wall Observer.  Thanks!

Also: antivirus software is useless. What a surprise.

First-stage payloads uploaded to VirusTotal here and here showed that at the time this post was going live, none of the 68 tracked endpoint protection programs detected the malware. Researchers so far have been unable to obtain samples of the follow-on payload.

Antivirus software has always been a scam.  No wonder McAfee got rich off of it.

Solution:  Don’t run executable code from unknown sources.  This means, among other things:  Disable Javascript!

Reminder: don't trust password managers...

A txt file, in a vera(true-)crypt archive is probably more secure, especially if it only contains a cryptic description or hint of the passwords. (still wouldn't use it for btc stuff)

That is such bad advice that I honestly can’t tell if you are trolling.  Stop it before someone gets hurt.  Do you also generate an ad hoc Bitcoin keypool with dice rolls and store the private key WIFs in a text file, so that you can avoid installing wallet software that may be backdoored?  Rube Goldberg wants his security systems back.

Password managers are only for the dumb and demented geezers who can't properly memorize a few hundred of unique, secure passwords (say >10 chars, including upper/lower, numeric and special chars and no known words). That's the same sort of pussy dimwits that needs to write down their seed phrase. *shaking head in disbelief*
Real men have a photographic memory and don't need crap like password managers, paper wallets or backups. Or do you really think Chuck Norris would use a password manager or backup data?

* psycodad ducks, runs and goes backuping his passwordsafe database files..

This time our TA worked out very well. If Bitcoin break resistance at 57K then we might see new ATH.

Chuck Norris tried to use a password manager once. He logged into the app and all it said was:
"Hi Chuck, I'm not even going to pretend that I can suggest a password that is stronger than you can come up with or pretend I can store any passwords as well as you can. Thank you. Please click here to exit the program."

Good morning Bitcoinland.

Back up over $55k... currently $55037USD/$68270CAD (Bitcoinaverage).

We still have a couple of days to turn April's candle green.

Go Bitcoin go.

Lol, my only question is why is proudhon aka llama in the drawing

Proudhon is an alpaca, not a guanaco, llama or vicuna.

Alpaca socks were one of the first (legal) products available to be bought with Bitcoin.

Thx for the info, didn’t know that

Anyone old enough to remember the Number Stations broadcasting out of Eastern Europe during the years the Berlin Wall was standing? They were used to communicate with intelligence agents, who needed nothing more than a SW radio to anonymously receive messages.
The Stations used high power short wave transmitters, the broadcast would start with a signature tune often from a worn stretched tape or a Station number ID.
Then a series of numbers would be read out by the announcer or voice synthesizer.
They were always in blocks of 5.

So 2-7-9-0-4 then 9-4-3-6-4 and so on.
Decoding could be by the use of a one-time pad or simply a book.

Where
digits 1 and 2 could be the page number.
digits 3 and 4 could be the line number
digit 5 the position of the word in that line.

The numbers then decoded to reveal the message.

The application of this for Bitcoin could be to code your wallet seed phrase in this way by choosing a book and finding those seed words in the book and converting them to 5 digit numbers.

Then writing down and storing anywhere the series of meaningless 5 digit numbers.

Without knowing from which book and the exact print edition (your key), your seed phrase is reasonably safe.

The cryptographers here will be able to punch holes in this but for good enough protection for regular folk it could work quite well.

[nullius]

I had been using a password manager for a while, But my Bitcointalk account outdated my password manager usage, so I never generated a password for it, was too lazy, learned my lesson the hard way.

Glad to hear it.  Good luck keeping your accounts secure, especially now that you have a Platinum account.  You wouldn’t want for anyone to steal Star Platinum!

Password managers are only for the dumb and demented geezers who can't properly memorize a few hundred of unique, secure passwords (say >10 chars, including upper/lower, numeric and special chars and no known words).

LOL.

Oh, by the way, 10 chars?  Considering only random case-sensitive alphanumerics, since many sites choke on special chars:

Code:

$ bc
l(62^10)/l(2)
59.54196310386875208867

A Hashcat guru would need to chime in with some numbers on the cloud-cracking GPU cost to bruteforce it.  Pretty high, I guess—but not high enough for my tastes, especially not with many sites using SHA-256 (or MD5).  It is definitely within the realm of feasibility for hardware that humans are capable of producing, without requiring enough energy to boil the oceans.  Too short.

Code:

l(62^20)/l(2)
119.08392620773750417735

Wow.  Not being cracked by Hashcat!  I know that at least one of the popular password managers uses 20-char passwords by default.  I won’t name it, because it’s a closed-source cloud thingie, and I recommend avoiding it; but that is a reasonable default, IMO.

Code:

l(62^40)/l(2)
238.16785241547500835472

The security margin here is basically free, so why not?  Use long passwords on sites that allow that; use max-length passwords on stupid sites that limit you to 12–16 chars, or whatever.

Yes, I am inappropriately misapplying Shannon entropy.  Most people commit this error when estimating password strength.  If we are treating passwords as random strings, what we really want to know here is the min-entropy.  Most people make this mistake from ignorance; I hereby do so from laziness, and because once we get up to a 40-char password, the security margin is so astronomically huge that none of this makes much of a difference.

Also, if your password manager uses a bad algorithm to transform random bits into an alphanumeric string (or whatever), there can be a significant bias; in the wild, I have seen password manager code that will easily let you lop off 30% of the search space, if you know (or can guess) that the target used that particular password manager.  Astronomically huge security margins do help here:  Losing 30% of the search space for a 10-char password could make a real-world practical difference; losing 30% of the search space for a 40-char password is only a theoretical problem.

* nullius 8> security margins (within reason).

That's the same sort of pussy dimwits that needs to write down their seed phrase. *shaking head in disbelief*

My brainwallet is “correct horse battery staple”.  I will not forget it!  And it is such a nonsense phrase, nobody will ever guess it.

A .sig I that once saw on—I think it was actually on Usenet, though I don’t recall:  “Real Men don’t do backups.  Real Men cry a lot.”

* nullius programs his custom password manager by punching hex opcodes into the front panel, because Real Men don’t use compilers or assemblers or pussy hand-holding n00b stuff like that.

Yes, they will.  So don’t do it.

No, it is not “good enough protection for regular folk”.  Not when in the real world—not in theory, but in practice—there are blackhats doing a batch offline attacks using any text corpus you can think of.

In a roundabout way, you have reïnvented your own version of the brainwallet.  I snipped the part that you said about number stations, because it’s irrelevant:  You are introduced your scheme by discussing some spy stuff that often relied on secure randomness, then discarded secure randomness.  Don’t do this.

Decoding could be by the use of a one-time pad or simply a book.

One-time pad = secure randomness, by definition.  (And if it doesn’t use secure randomness, it is not a one-time pad!  Also, by the way, in modern cryptography, “one-time pad” is often a red flag for snakeoil; a one-time pad is itself secure, but the term is so abused by ignorant fools that it has become a mostly reliable marker for a high probability of bad crypto.  A one-time pad and its information-theoretic security proof are altogether totally irrelevant to Bitcoin wallets, so I will further ignore this.)

“Simply a book” may have been adequately secure for some uses 50 or 60 years ago.  Not today, when a computer can easily grind through trillions of phrases guessed from a text corpus.

Please do realize that cryptography has changed.  In the WWII era, and for most of the Cold War era, the very best ciphers would be laughably insecure by today’s standards.  Accordingly, cryptanalysis was different.  In real-world use by militaries, the use of cryptography was quite often only to slow down the cryptanalysts for long enough that a message would be irrelevant:  A general doesn’t care if his “ATTACK AT DAWN” message is cracked after the dawn attack has already occurred.

To give you a quick gut-shot feeling for how much cryptography has changed, without getting too technical:  Cryptanalysis departments used to employ teams of experts in (human) languages, to assist with estimation of word frequencies and letter frequencies in the plaintext.  They don’t do that anymore—not the same way as they used to; not nearly—because modern ciphers output ciphertext that is indistinguishable from randomness for a computationally bounded attacker.  If the type of probabilistic cryptanalysis used decades ago could shave even 1 bit off the security margin of a cipher like AES or Chacha20, then the cipher would be declared to be badly broken!  Alan Turing could drawn up his “Eines List”, way back when—nowadays, that type of analysis is generally unhelpful.

Anyway, I hope you get my point:  There was a time when for certain uses, if you understood the threat model very well, then maybe you could use some phrase from a printed book as a secret key.  That is completely inapplicable to Bitcoin wallets.  Using a phrase from a book as a Bitcoin brainwallet is a most excellent way to run a high risk of getting your money stolen; and advising others to do so is a way to make them risk getting their money stolen.  Don’t do that!

P.S., if you still believe in your scheme, then please suggest it in the technical forum where you will be promptly roasted to a crisp.  I don’t have so much time to pick apart insecure brainwallet schemes anymore; I wasted too much time on that, for years.

Summary:  Use the free, widely available secure Bitcoin wallet seed phrase methods that have been designed and analysed by cryptographers, or else nullius may die of apoplexy.  Do you want for nullius to die of apoplexy? 

Also, do you want to risk having your money stolen?  Why mess around when the secure way is free and reasonably easy?

1 month from when?

Maybe better to use a more common parlance?  i.e... "In two weeks^tm"

So the 70k heslo in 1 month guess is back on the map....

70k by may 1 for sure

Oh gawd...

And still the "dump BTC for ETH or XRP" pump trade continues.  

Gosh do they want people in anything *but* Bitcoin so badly...  

I wonder why? Smells like 2017 all over again...
