681  Economy / Speculation / Re: What will BTC 'Mean Reversion' be in 2019? My prediction is $1400 USD on: November 28, 2018, 03:58:09 AM
Billionaires are funding their own separate chains, BCH & BSV
1.  They are selling any btc they still mine and using it to fund their forks.
2.  They also have huge amounts of btc to sell.

The BSV team plans to run this way for months to crush the other bitcoins.
So btc holders are going to be taking it on the chin for the foreseeable future.

No matter, what you think of Wright, his goal is to make Wu bleed money,
and constant selling of bitcoin to fund his operations in addition to making Wu spend more to support bch is a way to accomplish it.

Your $1400 prediction for btc is a definite and real possibility.

 Cool


FYI:
Anyone buying btc above $2000 now is going to regret it within 3 months.  Wink

The point is mean-reversion, until BTC stabilizes nobody can do quant math, and figure the risk,

The recent insanity aka "2017 bitcoin bubble' took BTC to the moon, now it falls back to earth, where does the falling stop? Well IMHO at the point of entry where all the fools came in, and that could be as low as $400 USD.

FYI, I would NEVER BUY BTC, I would MINE it, and if your young I would say 'salvage' it by running software that looks for lost-coin, as that is much more profitable than mining. Liken this to a metal detector on the beach, your more likely to find a gold ring on the beach, than a nugget in the mountains. See www.inflection.top, to understand what I mean by "bitcoin detection", finding lost coins.

IMHO Satoshi never intended for BTC to be traded like a cabbage-patch doll, that's zero sum game. If your using BTC to move wealth around the world and get it IN&OUT of the 'matrix' that would be a good short-term use of BTC, but long term BTC is not a safe place to 'park' wealth, unless you mine it, e.g. get it for free.

In stock market ~
bitcoin is not stock market.

Now of course artificially in 2017 BTC was to the moon because ~
wrong, it was because of a huge increase interest towards bitcoin in 2017 which led to money pouring in. and like always when the adoption/demand increases in a small market with thin orderbooks the price shoots up.

Quote
My prediction calculation is $1400 USD, about the same as an ounce of GOLD. Which would be fine with me if BTC just settled in parity with GOLD.
What you say here? Have an opinion?
if we are coming up with random numbers i say price is going to be $200000 about the same as a Lamborghinis so that it can settle in parity with it.

The whales are NOT done unloading, the whales are NOT idiots, HODL is for morons, billionaires ( whales ) didn't get rich by being morons.

BITCOIN is a  synthetic asset traded on exchanges for US Dollars.

Its a trade-able asset, of course its trade-ability is very narrow, as only geeks will except BTC.

The money poured into BTC in 2017 came from easy FED QE, and credit-card's, both these feeds have been closed post Dec 2017.

Today there is no source for "GREATER FOOLS" to enter the BTC pigpen.

Most of the whales ( think winkelvoss ) want out, but those that didn't get out at $20k, are well they're screwed Smiley

Like all statistical 'time series' the BTC historical prices can be analyzed by "QUANT PROGRAMS", and the future prices can be predicted to statistical certainty's.

All great PONZI's in history, Madoff including, tulip mania, .... et-al the call of the day was always "HODL".

...

The point is that BTC is not going away, its useful; It's now 10 years old, and in time the price will stabilize, and people can with certainty determine its 'risk', for now BUYING BTC is just burning good money.

We really can't 'value' bitcoin, but what we can do is let all the post January 2017 idiots wash-out, and that means bringing price back to $1,000 USD, and then let BTC find its 'sweet spot'

You can't make money by buying bitcoin.

You can't make money by mining bitcoin.


The only thing I can see is a perhaps a Mutual Fund in a place with cheap-hydro selling btc shares, based on cheap mining,

Last year ONE BTC was 20 barrels of oil, that might have been around at the $15k level, so say we're down to 5 barrels of oil now to mine one btc, that's still a lot of energy.

We can't talk about 'limited' because the clones dilute BTC, it's not like GOLD where people would actually BUY fools gold ( alts )

Maybe some new algo, or HW will come along to make BTC mining profitable again?? The thing is if mining ain't profitable, then why run a server or a miner? The entire premise of mining is to process transactions. If servers are only ran to collect a toll-tax, then in theory there goes the entire reason for BTC, e.g. free transfer of funds.

This is why I like the ZEN model, where people are paid in zen for running transaction servers, in time something like this will be needed for BTC.

Sure if the difficulty goes down, the price of energy goes down, but there are so many antminers out there, for now it appears that most bitcoin will only be mined in places with near to free electricity, of course 'true believers' can waste their money and pay a premium to mine, but again this is a fools game.

...

At the end of the day, BTC has ONLY ONE utility, and that is to move money from A to B, in a time of War where you can't carry your wealth for fear of government theft, ...


683  Bitcoin / Bitcoin Discussion / Re: Mining Bitcoin Forks Has Become More Profitable Than BTC Itself, Miners Pull Out on: November 28, 2018, 03:30:19 AM
You know the constant slander of any coins the btc zealots consider not btc, is really a sign of child like stupidity.

They call all other coins shitcoins, when the fact is many of those other coins outperform bitcoin in a multitude of ways,
faster speeds, energy efficient , built in anon, higher onchain transaction capacity and greater profit margins during the same time periods.

And many people have made money off of those altcoins.

Fact altcoins have made some people money and lost some people money , just as bitcoin has made some people money and lost some people money.

So if all of those superior designed altcoins are shitcoins, then bitcoin is the worst shitcoin of all.


 Cool


Corrections:

1.) Shitcoins have made the people who promoted them some money. Anybody that BUYS shitcoins is fool that will lose his/her money.
2.) All alt-coins are shit, because they're created by idiots who think they can copy & paste the open-source BTC code, and that be renaming stuff they're adding value, the only thing they have done is dilute the bitcoin brand.
3.) There is nothing 'faster' is all the alt's are based on the same code-base, using the exact same source.
4.) There is nothing energy efficient about different kinds of hamsters in their cages running in circles, all crypto computation is wasteful.
5.) I do concur that zcash has added value because they have embraced 'privacy' with their notion of the 'z' address.
6.) All transaction's of BTC clones are the same, of course BTC is going to be slower, because they're getting +90% of the transactions. An idle clone with no users, will always be the fastest.
7.) Alt-Coins are a result of 'open source', it makes it all too easy for an idiot to change a few lines of code and promote a clone, and hope to get 1% of the BTC volume, trouble is today there are +2100 clones, all trying to get that 1%, but logic will tell you they will at best get 0.05% of the crypto  eyeballs or less. Alt's are no different that 'penny stocks', they're promoted by con-men who get 100% commission on the sale. The people that 'invest' in penny-stocks and alt's are sheep, Muppets as they're called by Goldman Sachs.
684  Bitcoin / Bitcoin Discussion / Re: Mining Bitcoin Forks Has Become More Profitable Than BTC Itself, Miners Pull Out on: November 28, 2018, 03:20:03 AM
the way bitcoin mining and profitability of it works is based on difficulty. miners didn't pull out of bitcoin. SOME miners shut down because price dropped, they didn't do it because some shitcoin was created.

with that said when a shitcoin is being mined with a price that is low there is a stable hashrate. then when you pump that shitcoin up suddenly in a day or two it suddenly becomes more profitable to mine but for the miners that are already mining it. the rest aren't going to jump on board immediately to mine that shitcoin. and when they come it again becomes less profitable as the difficulty rises. and interestingly enough when the dump comes it becomes less profitable, you even lose money if you mine it because the difficulty is higher while the price has dropped.

saying "hundreds of miners have shut down" is just nonsense because first of all you have no way of counting how many miners are there on the network, you can only measure hashrate. and that is about 10-20% if i am not mistaken.

Exactly, also just because you can mine a shitcoin, doesn't mean you can sell it,

Right now BTC with a S9 will net you -$1/day, that means if you run a antminer you lose $1/day.
Some of the alt's claim, if you run the same miner, you'll make a $1/day, how about the cost of that miner??

Like I said, if you look at 'slippage' ( cost of getting in out of a thinly traded shit-coin ), then your going to net-zero.

Every CLONE of BTC is a shit-coin, they offer no advantage, bring nothing to the table.

However I think zcash is ok, ETH sucks hard, all the ICO's are bullshit. The only thing that would get me excited about a BTC clone is if they made it 10X stronger, more secure and more private than mother-btc, and I don't see that happening the powers that be, that run BTC want to keep easy for GOV to track, and imprison the population.
685  Bitcoin / Bitcoin Discussion / Re: Gold has been down 90% Nobody said "Gold is Dead" - BTC is the New Gold - Right? on: November 28, 2018, 03:14:34 AM
BTC is limited and it will end soon and the price rises to $ 10,000. This can happen in the next 5-7 years. I think you don’t need to compare with gold, because Bitcoin has noble goals

Wow! I said this to my friend exactly same words today Cheesy I didn't mentioned 10k $ but I told him that it's goin to be 200%+ value. People are getting more and more knowledge about crypto each day what is good. Bad thing is that there is a lot of negative

NOBLE GOALS? Pray tell what are they?

BTC is a religion, its founder is a ghost, the promoters are get rich-quick conmen who prey on the dumb. BTC is much like Scientology.

There is the technology of BTC which is 'good' in the sense of code that works, but the people involved in BTC are 99% get rich quick con-men, really PONZI-PEOPLE. BTC is not a ponzi, but those who promote the exchanges, and all the non-sense associated with HODL are Ponzi-People.

BTC cannot rise like the past, because the balloon has lost its hot-air, the rise in 2017 was from FED FIAT, and credit-card debt, both have been taken away from the party. Now idiot will have save their penny's to buy BTC to get a rise, don't count on the rich investing in BTC as those would did, and the majority would sell out if they could cover that did buy in, BTC still has a long way to go down, before it can even stabilize and find its mean-reversion.
686  Bitcoin / Bitcoin Discussion / Re: Gold has been down 90% Nobody said "Gold is Dead" - BTC is the New Gold - Right? on: November 28, 2018, 02:42:10 AM


The use case of good cannot be compared with that of Bitcoin not to mention how long and what it took gold to stand firm till date. To me, Bitcoin is still in the infant stage and still got a long way to go before it can be compared to gold.

The comparison is that both have a 90% volatility risk in their recent history.
687  Bitcoin / Bitcoin Discussion / Re: Gold has been down 90% Nobody said "Gold is Dead" - BTC is the New Gold - Right? on: November 28, 2018, 02:39:56 AM
That is true, i think it is because the price of gold is stable. Even if gold price down, it will going down with a slower rate.
Different with cryptocurrency, cryptocurrency have possibility to falling down greatly in the market because it's price is not stable.
Volatility is the main characteristic of cryptocurrency, and the main difference with fiat currency and gold.

But GOLD isn't stable, its historic volatility is just like BITCOIN today

The only thing that can be said for either is BUY low and SELL high, this HODL non-sense is for maroooooons.

Like I mentioned above, BTC is only as good as the ALGO for encrypting the key, and NO algo ever released by NSA has gone for more than around 10 years before its cracked. 

Well fiat-currency is backed by MURDER, CIA with its ownership of the worlds drug trade, only exists to force the world to use US-DOLLAR to trade heroin, cocaine, ... US-MIL forces the world to buy oil in USD, this is the power of FIAT, BTC has no such power.

GOLD of course is not backed by death,

Most likely the future of crypto is a super-computer that has an incredibly powerful encryption algo, that is the only way to make crypto-currency safe, but on the other hand the little-people will always make a PGP, and one-up the GOV, and the GOV will always come out with a new SECP256-k1, and the NSA will continue to have 'satoshis' feed new cryptos unto the sheeple.
688  Bitcoin / Bitcoin Discussion / Re: Gold has been down 90% Nobody said "Gold is Dead" - BTC is the New Gold - Right? on: November 28, 2018, 02:32:13 AM
Hmm,

Do you know what happens when the price of gold decreases,
the utility use of it increases.

Meaning more gold is used in Jewry , more gold is used in electronics, more gold is used in dentistry.

Basically the lower prices gold has other uses absorb it supply and help maintain price over time.

Bitcoin only real use is as a payment system , no matter it's price.
Many fools try to say btc is a store of value, the recent 80% loss in value should give those idiots a clue.
  
Low Price BTC is used as a payment system , the higher btc price the less effective payment system it becomes, as transaction fees become excessive.
BTC HAS NO OTHER REASON FOR EXISTING, and no other usage to offset a price drop.

BTC is INFERIOR TO GOLD & SILVER, because of it's lack of utility and dependence on ASICS miners that can't maintain profitability due to an energy waste issue that has been completely ignored since 2013.

If the ASIC miners quit, btc dies, no one can quit and your gold quits being gold.

Gold's other uses remain and no one needs to spend millions of dollars per month to keep it running like btc.


Sorry, I only see one use for BTC, and that is to move wealth during war.
Take the holocaust, if it were to happen today, people couldn't hide diamonds/gold on their person, the Nazi's now scan for all this stuff, so people need a way to move their wealth out of regions of war and start over.

For 1,000's of year in ASIA people kept a bag-of-gold on hand, and during an attack, farmers would grab the gold, and a little food the family and run like hell, and start over.

Today its still this way, but NOW governments are in control, and they plan to "Asset Forfeiture" everything

I don't see bitcoin as a 'bank', I see bitcoin a CONDUIT and nothing more, GOLD is great cuz you can bury it, you can't bury BTC, and its 1/2 life is no longer than the time it takes to crack ECDSA -SecP256k1 ( 12 years on average to break a new NSA algo ), but for short term moving wealth BTC, is where its at this point in history.
689  Bitcoin / Development & Technical Discussion / Re: In case of a 51% attack, can the damage be reverted? on: November 28, 2018, 02:13:29 AM
2- Limited  user vulnerability: The main targets of 50%+1 attack with its short-range chain rewrite consequences are merchants and exchanges that do not take proper security measures by waiting for enough confirmations (blockchain growth) for high stake transactions. This vulnerability could be mitigated if users closely observe the network overall 50%+1 attack cost and wait for more confirmations up to safe thresholds.

I think this piece of code in JavaScript could help merchants to understand how much confirmations would be enough for their trades - so mitigate the vulnerability. Wallets could generate such information for end users:

https://people.xiph.org/~greg/attack_success.html

That's the thing about 51% attacks though, there is no safe confirmation count for as long as a 51% attack is going on.

To illustrate:

Code:
AttackerSuccessProbability(0.51,1)=1
AttackerSuccessProbability(0.51,6)=1
AttackerSuccessProbability(0.51,100)=1

The question is then not how many confirmations suffice, but how long an adversary can hold 51% of the network's hashrate.

At what date did 'ANTMINER' go live? That's when BITCOIN entered the 'matrix', you can take the red pill or blue pill, the blue pill you ignore the 500LB gorilla ( china, alibaba, antminer,amazon), red-pill you deal with reality.

since antminer went live, they control 90% of the bitcoin mining, that means that whatever they have been doing since then, they have been in control, as they decide the consensus, and nobody else,

funny thing about these red/blue pills is that this site right here is hosted by amazon-services, who is tied to alibaba, who is tied to jack-ma, who own majority interest in antminer, and jack-ma just got entered into the communist party of china, this is a big-deal

continue on folks, live in the matrix, and this time its brought to you by amazon/alibaba

Another way to use the MATH is apply the 'Kelley Criterion', as the differential eqn, optimized solution for max wealth is all the same, 2P=F, once you hit 50% ( 0.5 ) then your in 1.0, say china ( alibaba/amazon ) control 90% of bitcoin mining ( consensus ), then they're 1.8, ownership/control and some more

More interesting thing about the Matrix, and china's social-score ( facebook ), is why would amazon/alibaba want to control all the digital-money on earth, when they already control all the shopping? Why even ship a product, when you own the printing press? Me thinks this is largely a supplier problem, as suppliers to the GORILLA can be PAID in 'crypto fiat', and of course the sheep who work in the factory's too can be paid in crypto-fiat

The Matrix is Real.
690  Bitcoin / Bitcoin Discussion / Satohsi's Math ( Original Paper ) clearly stated BUYING BTC would lead to Ruin on: November 28, 2018, 12:57:05 AM

BTC is a winner, if you survive 1-3 years in biz, your a winner, btc is now 10 years old that is SURVIVAL big-time, BTC is already geriatric;

The saddest thing for me is that BTC instead of being private & secure, has become just another LOTTO for sheep, where lotto is a tax on stupid people, bitcoin is a tax on geeks.

BITCOIN was to be MINED, not bought, if you mined your costs were ZERO, if you bought, then you lost.

Speculation ALWAYS leads to gamblers RUIN, especially when you put in the entire pot.

Study 'kelley criterion', the guy wrote the book on investment calculus, F=2P-1, where P is the probabilty of the win, and F is the factor of how much you invest.
If you have a 50% chance of winning you invest zero, if you have 100% chance of a 90% loss like bitcoin, then you sell 10% of your NET-Worth. Unless you have a 100% chance of winning, you don't bet 100% of your net, in the case of BTC, most people went on credit-cards and bet their entire net-worth, with a 50/50 chance of loss,

The smartest move was to buy ZERO.

BITCOIN uses the same math, its in satoshi's paper the entire '51%' double-spending problem is based on the theory of enormous numbers invented in the 1700's. Only when 'sure thing' exceeds 50% do you 'invest', but even then, only a small fraction of your net-worth.

The entire BITCOIN scam is the class 'gamblers ruin', to the poor-house, wiping out all your wealth.

BITCOIN was meant to be MINED, not bought, when you mine bitcoin, you have a sure-thing, for a known cost ( investment ) you get a known return probability of 100%, but of course TODAY mining is NEGATIVE, that is it costs more in electricity than the value of BTC, so you don't mine, and you don't buy.

At what 'floor point' in BTC do you buy? Today we don't even see a floor in the current horizon, perhaps in a year or so, we can use mean-reversion, and predict a certain-profity percentage, and using kelly-criterion get an investment fraction, but today you would be better burning your money if your goal is total loss.

Today 'trading' bitcoin is flipping dice, and that is 50/50, and that's a game for retarded people.

Satoshi knew the score, his baby is based on this math, if your going to use BITCOIN, then use the math that goes along with bitcoin.

You mean we have to distinguish between Bitcoin as a currency and Bitcoin as a technology.
The technology is a revolution in itself and no one can deny this fact.
Unfortunately, 99% of Bitcoin users are interrested in the currency and how to make profit from it which is not helping the technology.

BINGO we have a winner, especially this forum, its should be called the 'bitcoin-talk-to-moon-org'

Truth is no one knows.

TRUTH is EXPERTS KNOW

Truth is there is nothing new under the sun

Truth is BTC is down 90% year-to-date, and statistically it can go down this year another 90%, and this is the TRUTH.

You can't lie with math, it could also possible go back up 90%, maybe but then it would only be back near $7,000.

This is truth.

Truth is there is NO BOTTOM except zero, but BITCOIN is here to stay, and most likely it will mean revert back to near $1k, and float around that region +-90% for years to come.

I don't get it. They don't allow the Internet to be used on the public, then how can they possibly use Cryptocurrencies? Is it only the government exclusive thing?


Thats true how to explore cryptocurrency if the internet connection can't use publec community in north korea, if government of n. Korea want to explore cryptocurrency they need to allow community to use internet and need to be open minded about transaction relationship to other countries.

We don't really know the truth do we? We do know that south-korea is more tech advanced than the USA

I also know that these same people sponsor these 'seminars' all over ASIA, and bring in the normal celebrity speakers, and host the exchanges ( sell boothes ), that 1,000's  of newbs spend $1,000's  of US dollars to attend these seminars, and that exchanges, and all conduits for separating idiots from their money work just like magic.

The fact that the same thing would happen  in NK? Why not, they have money, and where ever there is money, this group will flow to shear the sheep.

I travel widely all over ASIA; I don't see any reason that 'elite' don't have internet access in NK, maybe the low-class, but that's more of an information control thing, the leadership of NK wants to modernize ASAP, so what better way than to put the internet into the hands of every NK child, and then NK can overtake SK in TECH.

Canned 'bitcoin summits' are running monthly all over asia, what makes a summit? Maybe they bribe or pay one or two authors who might have written a book about bitcoin, then have a ton of other people give talks about how they got rich on crypto's back  in 2017, or how if you had bought BTC in 2009, that you would be the richest man on earth today Smiley
694  Economy / Speculation / What will BTC 'Mean Reversion' be in 2019? My prediction is $1400 USD on: November 27, 2018, 11:40:21 PM
In stock market the typical 'quant' method to make money is mean-reversion, you study all stocks and calculate their trending-average, then using lin-alg, you can get eigen-values and predict stocks that are out-of-whack, high(SELL) or low(BUY), and when (time-factor) they will revert to their mean.

Now of course artificially in 2017 BTC was to the moon because of the FED ( free fiat to infinity post 2007 ) & credit-card ( banks let morons go wild - 22% debt to lose 90% wealth )  purchase of BTC, both those windows are now closed. Thus BTC will now drift lower and find its mean.

My prediction calculation is $1400 USD, about the same as an ounce of GOLD. Which would be fine with me if BTC just settled in parity with GOLD.

What you say here? Have an opinion?

I see no possible 'moon shot' on the horizon, we're looking at a down market, people are cash-poor, deep in debt and shit is going down all over the world, thus there is no new source of funds to flow to BTC.

The whales are NOT done unloading, the whales are NOT idiots, HODL is for morons, billionaires ( whales ) didn't get rich by being morons.

Post Dec 2017, futures trading became possible with BTC, so whales could 'buy insurance' when they sold tons of BTC, so the question is are they done selling?? I don't think so, I think everybody is waiting to get past the new year.

BTC had settled to $6500 zone, now its on the $3500 zone, soon $1700 zone, I think it will bounce between $1000 & $1500 for a long time, all the post January 2017 gains will have gotten wiped out.

THis is no problem folks, had you owned gold in 1978-1982 you would have also 'lost' 90% of your money, but had you sold high, and bought back in low, you would have also 4X your gold holdings.
695  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: November 27, 2018, 11:25:17 PM
Hi all,

I've been working on a tool for brute-forcing Bitcoin private keys. The main purpose of this tool is to contribute to the effort of solving the Bitcoin puzzle transactions: https://blockchain.info/tx/08389f34c98c606322740c0be6a7125d9860bb8d5cb182c02f98461e5fa6cd15

Screenshot:



It is open-source under the MIT licence and requires no external dependencies other than the CUDA toolkit. It builds on Windows using Visual Studio 2015, and Linux using Make (you might have to edit the Makefile and point it towards your CUDA toolkit directory).

It can search for compressed/uncompressed keys or both.

The performance is good, but can likely be improved. On my hardware (GeForce GT 640) it gets 9.4 million keys per second compressed, 7.3 million uncompressed.

Note:
-Currently it is CUDA only.
-It can only search one target key at a time


Features I would like to add if there is enough interest for the project:

-Support for searching multiple target keys at one time Done
-OpenCL/AMD device support
-CPU with AVX/AVX2/SHA support
-Checkpoints/Stop and resume
-Vanity address generation


Source and Win32/Win64 binaries available here:
https://github.com/brichard19/BitCrack
https://github.com/brichard19/BitCrack/releases/tag/v0.0.6


Thoughts?


Thanks!

I wrote a package last year called 'inflection', its detailed on www.inflection.top, but I have been working on this problem since 2012, and I was an early miner, but I always found BTC-HACKING, e.g. solving the 'discrete log problem' more interesting than accumulating btc.

All the things you have asked for have been done,

But I might add that 'brute force' hunting is not the way to go about this problem, like the other guy 'LBC' linear collider, its stupid to search 1-N, where N is 2**256, as that is counting all the atoms in the universe, many times over. It can't be done, unless you have an infinite time-frame to solve the problem,

The way to go about this is INTELLIGENT selection of the seed for searching the frames ECDSA, also using SAGE and MSEIVE ( most powerful factoring tool on earth ), you can factor public-keys, and develop a good band for your search, also using FFT, and RNN-LSTM you can generate favorable regions for searching,

My software that supports all GPU HW, currently does 150M/sec calcs per 1060 class card, so on a typically GPU rig for mining, I can do over a Billion calc's per second, but that is still just 10***9, where our scope is say 10**77, and there are 10**71 atoms in the universe.

Also I don't think its possible to find a particular key for a particular address, the way to go about this problem, is I have 200 million addresses with value, and 100k with high-value, I use a four layer hierarchical bloom-filter that starts at 2*32, and goes up to 2**40, everytime I find a priv-key that matches my list, there is 0.0000001% chance of false-positive, that one in 10 million, but I'm doing a billion a second, so I'm geting a lot of false positive hits, so as candidates are found, they past to the next heirarchy of bloom filters, so I can kick out up to one in a billion false-positives, I usually dial this stuff in so I can about 100 candidates a day, then its easy to use the database online to check if the key found has a 'current value', if > 0, then I log, I have found lots of 0.001 BTC, but the odd's of finding > 0.01 BTC are low, as we're talking 2*22 in a space of 2**128

So in reality here I'm looking for 200 million keys at once, not looking for one, and I'm using best estimates of likelyness to search in spaces

I think the most progress will be made in the area of sage/msieve using the published papers on discrete-log problem solving, if you want to find a particular key for a particular public address. Right now I have it down to 2**42, which is still to long to search, but with 2**24 at once, my search space is only 2**22, which is no problem

do you have an open source software ?

can you find the bounty transactions mabey faster with your strategy ?

Yes, sure I give out all the source to free to people in the third world, mostly India; The web-site is www.inflection.top, the github github.com/btc-room101, just tell me what you want,

I have 100's of tools I have written since 2012 when I started working on Bitcoin, most of the stuff is in python, and the gpu stuff of course is in C++;

I'm not inclined to put 100's of packages on github, so tell me what you want, I could make a list of what I have, best here is list what you want, and I'll tell you if  I have it, since I have done this crap for 6+ years ( hack bitcoin ), but I have been hacking crypto for 30+ years, so I have lots of code

I don't know what people want or need,

I think my site www.inflection.top discusses my areas of research, and the code, normally what I have done is from that site people ( usually students in 3rd world countrys ) send email and request code, I have found in the past that the 'guardians' of bitcointalk don't want anything real, they go out of their way to protect bitcoin, but as an intelligent person knows, knowing this stuff makes you strong, but instead the community prefers the continue the cannards and lies that has made them 'virtually rich', not unlike the little-prince ( a book ) where a man owned all the stars.

I would lke to see BITCOIN stronger, but the PTB want to keep it weak, just like FB,GOOG,TWITTER there is a concerted corporate effort to take away all notions of privacy and security. Here in BTC they tell us its secure, that its private, and anybody who steps forward with the truth is censored. This will be the downfall of BTC that it is over-lorded by imbeciles. In the meantime the RUSSIANS, CHINESE, and INDIANS will leave the west in the dust.

One advantage of focusing on puzzle transactions is that finding (and taking) those funds presents no moral dilemma. It's meant to be a reward.

please clarify - how is finding/taking funds (essentially stealing) found to have no moral dilemma? and why would stealing be a reward?

or am I misunderstanding and there is no stealing being done and these are just free funds floating out there?

Why is solving cryptographic problems as a miner not stealing, while it is stealing as a key cracker exactly? Because you say so?

Mining a block is essentially the same as solving a puzzle challenge: the winner is expected to claim the funds.

Cracking arbitrary addresses - funds that belong to other people - is completely different. IMHO.

Well its a HOBBY,

You can photograph stars, but so long as you don't travel there and steal the star its ok right?

How about photo-graphing a lion at the zoo? That's ok, so long as you don't just the fence and go into the den?

For many of us we do this because they said "IT CANT BE DONE", that is a mission for many people,

With regards to what do you do with an address/private-key combo once its found? I would say nothing really, when I find BTC addresses and match their physical key, I used to sweep, but that was years ago, but I don't even own an exchange account, I know it would be silly to even buy/sell BTC, as its all tracked.

Most of what we call BTC is BIG-LIE, that its secure, that its safe, that its private, ... its all a lie, the only thing real is the MATH, the SHA (NSA), the ECDSA (NSA) that is all real, so cracking the GOV's code is what makes this cool, but actually 'spending' btc would be like jumping the fence and going into the lions den.

For anybody here that wants to learn how to crack bitcoin, lets talk the talk, and I'll share the code.
697  Bitcoin / Development & Technical Discussion / Super BrainFlayer 2019 - Enormous Blooms, Gigantic Text-Files, all BTC ADDRESSES on: November 27, 2018, 10:41:11 PM
Back in 2015 when Brainflayer came out I played around, and over two years I rewrote the core, and raised the bloom filters from 512mb to 64gb, and setup pass-word tables at 512gb, note your need a 4TB hard-disk to pretty much play with this stuff, and 64gb of RAM.

The other thing is putting bloom-filters on GPU cards, with a 1060 you don't really get 3GB of RAM for one allocation, its really like 512mb, same for 1080 card you don't get 8gb you get around 1gb, but once you know the maxes you can put bloom filters on the card;

Another thing is you need to harvest 200million addresses that have had value, and of course the 50k with high-value, and then run 24/7 to get the new addresses out of the mining-pool.

...

What is brain-flayer? Well its a program that was written to crack bitcoin addresses that used test-strings as their private-key, thus if you use say a 512gb text table, which is every possible combination of strings for every language on earth, ... and pass that though a GPU/CPU then run through keys for every possible 'string' then you can find all the bitcoin accounts that used 'brain-wallets' ( another word for using a string to generate a private-key )

The unique thing about brain-flayer is that it used bloom filters to keep track of the addresses of high-value, so this way as it ran and matched an address with a key/pair then the private-key/address/pass-string get printed out, so you can generate 1,000's of private keys that all at one time contained value.

Most of course are all drained, but its still interesting.

There are many parts to this puzzle, if people are interested tell me what parts of the above are interesting and I'll upload the code to github.

github.com/btc-room101

Given there are dozens of 'parts' to this package, I need to know what people need? I also did this stuff for ethereum as well, so that's available.

Just moving on, that's why I'm dumping the code, but I don't want to bother uploading to github.com if there is no interest.


...

The thing is this just isn't about 'test-string', or brain-wallets, there are many tests that can be done, as many people used block-chain 'data' as their private-key, so there are still tons of 'dust' to be found for those who want to bother.

Finally, let me say this I have found lots of BTC, and I just move-on, I'm not interested in collecting btc, as you can't sell it, its not private, it can't be sold, and I would never use it in an exchange, as its all tracked, so what would be the point? In fact I don't even own an exchange account.

I just find that HACKING BTC is very interesting, I have been involved in hacking DES, since the 1980's, and AES, and ESCDSA, so all this stuff is just an interesting hobby for me.

I think that you can start now. But do it carefully. My view is that bitcoin will continue falling to 2900. But after it, the new bullrun will start and it will be more faster and bigger.

I would say that 1/2 that, or about $1400,  I have long felt BTC would go back to around $1k, where it was begin of 2017;

It's more important that is 'mean-revert' and stay in that window, this 'moon-shot' crap is over,

BTC went to the moon ( $20k) because the kids were buying it on credit cards ( that's over, banks closed that window )
BTC went to moon because FED was printing free-fiat 2008->2017, that window is now closed

So now BTC will revert to the mean, and that means pump  around $1k,

I have always had the opinion that BTC should be MINED and NOT bought, but honestly the point of inflection has already passed, its now more profitable, to harvest 'lost' btc than to mine, this is largely because the antminer s-9 class machine are making a whopping -1$ a day, that's right, everyday you run an s-9 you lose a dollar. When BTC goes to $1,000 or less, then it will be what -$5/day

There are three ways to get btc,

1.) buy it ( the dumbest idea )
2.) mine it ( no longer profitable ), think this way it cost more to mine, than to buy it,
3.) write your own software to harvest, scan, or search for 'lost' btc, this is a good use of re-deploying those GPU racks

www.inflection.top

When is the best time to INVEST?

Well when your young, and you can afford to lose all your money. The problem is BTC now has a 90% volatility, its just as likley to go to $300 tomorrow, as it is to go back to the $6500 zone, but for now the trend is DOWN, because of what I said above with the closing of the FED FIAT, and the credit-card, there is no new money coming to BTC, which means now it slides down to its TRUE VALUE.

If there is a WAR anytime soon, in EU/USA, ... then I would expect BTC to skyrocket, as its a safer way to move money than GOLD. Other than that there is no way BTC will do anything other than bounce around and slowly revert to its mean-value.

So what is your opinion of the super-node? I think the current secure-node is ok, maybe the secure-node will pay for itself, mining sure as hell don't pay,

Now with the antminer for zcash, there is no point of mining, even if you have one of those boxes, let alone graphics cards,

ZEN will go south of $1, and I will pickup the 500 and setup a super-secure node for the hell of it,

With regards to "HORIZEN" the problem I have with that name is that HORIZEN is the dumbest, worst, most unsafe airline in the USA, why would you want to name your 'coin' after a loser that hires morons to fly and maintain airplanes?

It goes to show that TEAM-ZEN wasn't interested in marketing, that they brought in 'experts' who gave them a kardashian 'makeover', and left them with HIV,

Hey first rule in TECH is "If it works, don't fix it", I think before the marketing BULLSHIT began, ZEN was cool, now its like positioning itself for what? Morons? Newbs? Losers?

Early on ZEN, had it right focus on privacy/security, but then some test marketing people came in and said "This is not what sells", "Sex Sells", so now you have Horizen, the sexy new-millenial coin, just like their website, its clear that most of their 'work' goes into marketing and that damn website, how about some back-end coding guys? I now that brought out super-node, but really they need to step back to what got traction, and stick with that,

The corporation don't want security or privacy, they want open transactions, so everybody can see what you buy, where your at, ... blah-blah, ZEN bought its market-share on the promise of PRIVACY, and now they're telling us that its no longer important, now they're telling us that WHORE-CIA-ZEN is just plain sexy.

They say that MONERO/ZCASH is used by al-cia-duh, but ISIS is CIA, the ZEN people are cool because they come from NAVY-INTEL, which are every bit as smart as CIA or NSA; The potential is here don't screw-up ZEN with panzy bs.
700  Bitcoin / Development & Technical Discussion / Re: Is Blockchain a new technology or just a method of data storing? on: November 27, 2018, 10:41:35 AM
If you say blockchain is a data storing structure, do you agree it is one the worst database produced ever?

Your comment is very much analogous to "like judging the fish for its ability to climb a tree"
Block chain is not created for storing the data though it store transaction data.

Before Satoshi , people already proposed  electronic currency/Crypto currency. Even Satoshi was not the first to tell us about PoW consensus.
Everything was there and only problem is that we did not have any decentralized method that can work for distributed system (byzantine fault tolerance).
Block chain solved that problem.

It will be helpful if you read the below post and references mentioned there.
https://bitcointalk.org/index.php?topic=5066766

I will suggest you to understand CAP theorem and byzantine fault tolerance and you will get the answer to your current question.


Most will agree that Satoshi was not a very good programmer, he's clearly a math guy, that wrote code,

In terms of 'tech' nothing about btc is novel in the world of computer-sci, that means there is no nobel awards coming for satoshi@nsa,

Most of this stuff is right-time, at the right-place, many a people had tried to launch and digital-cash, this was the first that stuck to the wall,

The only thing novel in satoshis orginal paper was his estimation on how to solve the double-spending-problem, given that the chinese have long container +51%, its not even clear that problem has in actuality been solved, as its was assumed that BTC would be a peer2peer system, that not all the miners would be operating under one umbrella in china,

Lastly, Satoshi's paper isn't even interesting, as its a 100% clone of the prior BIS paper published in 1997, on how to make a 'digital bank', most interesting is that satoshi didn't even credit that paper, given that he copied it almost verbatim, other than adding his probabilistic solution to the double spending problem.
