give up and wait for quantum technology

Good evening,

I just added an AVX512 version of KeyQuest V1.3 available at https://github.com/Benjade/KeyQuest promising higher speed. Available only on Linux or via WSL.

Best regards

... But hey, congrats for not going the horoscope font size path...

I have a question and why two different private keys can lead to the same address in certain circumstances?
Example:000000000000000000000000000000000000000000000050574a424748444e47

libsecp256k1 has the fastest code to compute a public key from a private key.

Avoid computing from private keys at all costs. Precompute any public keys you know are constant (or any deltas that you know are constant), and do pubA + pubB in affine instead. If you have a batch of (pubA, pubB) pairs, use a single field inverse. If you also know that you want to compute pubA - pubB (for example, if all keys of pubB are distanced in identical deltas from both sides), move to the middle of the batch and re-use the same resulted inverse at each step to do both pubA + pubB and pubA - pubB.

Dump JLP, it is slower than libsecp256k1. Use the fe_* and ge_* primitives to generate public keys and implement affine point addition (the lib does A + J because it specializes on k * G, not on P + Q). Affine + affine is faster than A + J if you batch it and if you actually need affine points, not Jacobian.

Let's recap the main methods:

1. Magic-based

- Adobe Illustrator number horoscopes, misc. font sizes, arrows everywhere
- magic number patterns in hexagons, squares, rectangles;
- adding "hex" numbers left and right, maybe mix in decimals as well, so that we can fit somehow solutions


2. Random methods

- sliders to choose hex digits, maybe we get lucky by clicking the mouse!
- Python scripts that sit idle in background (we all like quiet environment, right?)
- pick random ranges, or random keys - ignore completely that testing 2/3/4/5/6/...N times the same keys or ranges becomes inevitable really, really quick, why care?!

3. Probabilities

- backward statistics: if something is probable, and it happens, than it can still be analyzed as if it was just probable, right? Sure.
- uniform distribution: if something is totally random, then it matters what values it ended up with (and also when), and hence we can predict where & when it's not likely to be repeated
- the keys must not look "not random": very low chances that the solution is key 0x1, or key 32768, 16777216, and so on. Because too many zero or one bits in a row. Even better, do the same with base-10 digits, or upgrade to using hex char strings. Also, invent some alphabet where hex digits are case-sensitive, and let everyone else figure out WTF you smoked.

4. Mystical

- hashes are broken; NSA has the backdoor to SHA256
- there is a hidden relation between secp256k1 formula and RIPEMD160 bits: this makes all sorts of statistical theories to not apply
- neural networks can be trained to predict the keys, because they are really so intelligent that they can predict the future.

5. A shitload of computing power, scanning the ranges just once by splitting the work. Keep some proof of work for each range, like keys for a fixed number of leading zeros. Laugh thinking that some people may interpret this as proof of backward statistics (maybe combined with mystical key-to-hash relationship) as the main reason of why the correct key was eventually found after around 50% checked keys.

I thought keeping bitcoin in bittrex will fetch me bitcoin gold as it gave bitcoin cash in the previous fork. but they have not yet credited bitcoin gold .i think those who had private keys with them they have claimed bitcoin gold successfully.

"  If you have a Bitcoin (BTC) balance on Bittrex during the BTG snapshot block 491,407 occurring approximately on October 24, 3am PT (10am UTC), you will be additionally credited the equivalent amount of Bitcoin Gold (BTG) on a 1:1 basis. i.e. 1 BTC on Bittrex held during the on-exchange snapshot will get you 1 BTG.  BTC held on orders will also be credited.  Only the BTC held on your account is eligible for BTG.  Full details below."

I sold my bitcoin today. I think the price jumped too much too fast. My opinion is that it will drop below 5,000 soon and in that case I will buy back again because i expect bitcoin to increase significantly in the long term.
What do you think??
Edit: If you are wondering at what price, i sold at $5720. I bought Litecoin with ithat money.

Next week a fork in bitcoin network will happen. What is your position about investing some money:buy, sell, hold or invest in other alcoins?

The number of successful ICO's are decreasing dramatically.  Just wanna know about successful ICO's in the fourth quarter of 2017 and if anybody still believes in  ICO's.

I'm just start into Crypto about 1 month, as people, i'm looking for a good ICO to invest with a dream that it will sucess and bring me some profit. But there is a lot of ICO incoming, some sound very good like HXT, Storm, Cryptaur or Electroneum. I'm really lost in those, i tried to do some research like people such as: their white paper, roadmap, v.v.. but i can't not found what is the best for me to start. Can you guys give me some advice or some trick to do a research.

Thank you.

There's a lot of distinct differences that could be drawn between the two.

1. Fiat can be created from thin air; cryptocurrencies has a set amount of coins to be mined/acquired.
2. Inflationary (fiat) vs Deflationary (cryptocurrency)
3. Region-restricted purchases (fiat); shopping with no borders (cryptocurrency)
4. Requires an intermediary to store money (fiat); you're your own bank (crypto)

These are some of the things that differ crypto from fiat. There's a lot more aside from those things but that's just what I thought off the top of my head.

why some country banned bitcoin?
is there any problem? i know that bitcoin is international crypto currency. but why some country banned this cryto?
