Everything connects well. Perhaps because of your location, there are some delays .. Yes, it is built on the API. But this is an honest business. The API suppliers give us a percentage of the transaction. That is, we do not take anything more from you. You laugh at the young project, it is so easy. More like trolling.

So, you didn't find a site and test it,  it's your website. Which make this:

 
I made a trial exchange and it was successfully completed ..

look really, really bad,  isn't it?

I don't laugh at it, I point out obvious mistakes, obvious flaws, obvious shilling, and the fact that you made false claims.
Also, coming back to your no KYC stuff, you seem to have forgotten to read some parts of the ToS of your 3rd party services:

Quote
Kindly note that we have AML/KYC policy;
Due to this policy, users’ transactions may be held for KYC procedures;
That is why, before users start an exchange via our API, please, notify them about the possibility of holding the transactions for KYC procedures;

So, although you will not ask for KYC if a user does a transaction though your website he might get asked for KYC, a thing you're not telling your users.
We had to pull every single detail out of your mouth with a forceps, how about you start coming clean and end this charade.

You're free to advertise your website be it a whitelabel, an affiliate page or not, I don't care, but don't try to deceive people!
Nobody is trying to deceive you. Unfortunately, some exchange limits have been increased .. I will provide you with more screenshots of the exchange. I managed to exchange 1590 Doge for Monero. But to exchange Doge for Bitcoin, you need 12000 doge at the moment. I repeat, if the site does not give you exchange address, then you need to increase the exchange amount.

I cannot show you the proof of the Monero transaction since Monero is a private.I'm sure a screenshot will be enough.Unfortunately, I don't have much time to answer you, but I hope that you saw the proof of the fair exchange. Thank you.

 I present to your automatic cryptocurrency exchanger. https://cryptoex.online/
How it works?
We use a technology which allows us to search the best market rate and exchange your coins trought different API's.
I wouldn't call that one an exchanger instead, it should be a crypto exchange "aggregator" that's poorly coded.

The address for sending funds will be issued to you as soon as you click-Exchange.
That didn't happen...
- It gets stuck in a page that says "CARREGANDO" which I believe means loading (checking the source code leads to the error that stompix posted).

I made a test exchange of Doge for Bitcoin,and everything went fine.
Perhaps you changed something afterward.

The site takes a long time to load, is the problem related to me or is the site running slow?
It loads normally on my end.

Is changenow's administration trying to get more money by creating many websites and working in the background, or are the developers lazy and want to make some profits?
I strongly believe this case is the latter one.

@vimp666
You should only announce a service/product when it's fully tested and not just do it for the sake of introducing something to the world.
- First impression is everything and you just ruined yours.
The proof of the exchange is in the first message.This is not a fake but a real screenshot. I made a trial exchange and it was successfully completed .. Yes, the site does not have information about the owner. But it also does not require any information about you.I can tell you with confidence - this exchanger is not a scam.The site design is not perfect, but the sharing function works well.

Nobody is trying to deceive you. The exchange takes place in a fully automatic mode. I wrote earlier that the exchanger does not require any confirmation of your identity from you. Registration is just an email and a password (mail may be temporary). The next time you exchange, you can create another account. Site owner. does not want to steal your money. If the exchange does not take place, then you need to increase the amount of cryptocurrency you want to exchange. The minimum exchange is approximately 35,000-40,000 satoshi in bitcoin equivalent.
4  Economy / Exchanges / Cryptoex.online Automatic exchanger between cryptocurrencies. on: September 23, 2020, 03:35:47 PM
 I present to your automatic cryptocurrency exchanger. https://cryptoex.online/

This resource exchanges any crypt for any other from the list. Only those cryptocurrencies are provided that are exchanged in any pair of the presented ones.

As I wrote above, this exchanger is completely automatic and works on the API. So the site owner has absolutely no access to your funds.

Registration is very simple - mail and password.

We do not send any confirmations to the mail. You can write any mail you want (everything is completely anonymous). We do not store any data about you other than your account data.

                                                                                      How to exchange.


1.-This is the address and currency you want to receive.
2.-This is the cryptocurrency you want to exchange. (I advise you to change at least 0.00035-0.0004 in bitcoin equivalent. API providers with smaller amounts usually do not work.)

3.-This is of course an exchange.
Exchange commission 0.4%.

The address for sending funds will be issued to you as soon as you click-Exchange. Send exactly the amount that you specified in one payment.
I made a test exchange of Doge for Bitcoin,and everything went fine.

Hi all,

So no one knows a pubkey to 64?
Address 64 has no outgoing transactions.Therefore, the public key is unknown.


so everybody seraching higher known addresses ?
Pollard's method can only search for those addresses where the public key is known. So the answer to your question is Yes.

it kinda looks like a general bitcoin clone, what makes this one different btw?
This coin is thrown by the developers. On all exchanges that still trade in BCX, the deposit is closed.Apparently some kind of transaction failure on the network. I do not think that the coin is worthy of attention. If only someone does not want to revive it. At the moment, the coin is dead.

kangaroo work with only one key.

You can run on a large list of public keys.
Telariust answered this question

https://github.com/Telariust/pollard-kangaroo/issues/3#issuecomment-530904845

Code:

@Echo Off
COLOR 0A

SET file=PublicKey0001.txt

setlocal enabledelayedexpansion

SET sessFile=_session.txt

SET Npubkey=0
echo [~] calc total Npubkey in file "!file!" ..
For /F %%a In (%file%) Do (
SET /a Npubkey+=1
)

SET lastN=0
IF EXIST !sessFile! (
SET /P lastN=<!sessFile!
)

SET n=0
For /F %%a In (%file%) Do (
echo =================================================
REM date /T && time /T
powershell Get-Date
echo [!n!/!Npubkey!] %%a

IF !lastN! == !n! (
echo !n!>!sessFile!

C:\Python37\python.exe pollard-kangaroo.py 32 %%a
REM timeout /T 1

SET /a lastN+=1
)

SET /a n+=1
)

1.And so Telariust answered>>>>>
Simultaneous pubkeys calculation will overly complicate the program.
And important: for N keys, performance will drop N times.
Sry, but i dont do it.<<<<
2.With this list of keys, the speed of the kangaroo will drop by 99,9%. I think so.
3.Let's hypothetically imagine that you found 1 key and received 1 bitcoin (and the address was 150 bitcoins. For an example). And the creator of this entire list took the remaining 149 bitcoins.
4.You don’t know the key space. Do you want to check the entire 256-bit range? You will not have enough remaining time until the end of the universe.
11  Other / Off-topic / Re: [ARCHIVE] Bitcoin challenge discusion on: December 18, 2019, 08:23:39 AM
2.5 gigabytes of public keys. Before starting the search, need to know how many bits are in the key. Or did the author collect all known public keys with a balance or invented them myself?And the keys are most likely changed. If you find a private key with 500 bitcoins, why do you share with someone? kangaroo work with only one key. And in what space look for a key? 0-256 bits?no one gpu kangaroo can no scan all 256 bits.scam.

Yes, that's right - I wanted to test this theory of two transactions with the same signature. Just one person began to pass this method as his invention, but I found information about this method dated February 2018.

I honestly said here that programming is not mine.
Something I can do, but my knowledge is very small. It's too late for me to learn programming.

vimp666 - I don’t know what kind of programmer you are, but I’m 100% sure that if someone gives you software with the "get rich" button, you will click this button (just like me). And what's the difference between us ?


why programmer ? running python scripts is not so difficult. I’m not telling you what you need write a script.scripts on github and without us are enough.I think almost all transactions with the same signature are a blockchain android wallet failure (a few years ago), which for several hours produced the same value of (k).
13  Other / Off-topic / Re: [ARCHIVE] Bitcoin challenge discusion on: November 20, 2019, 06:37:05 AM
Now the section "Get R, S and Z values from a Raw Bitcoin Transaction" on the 2coin.org resource often freezes and does not work.
Is there any other resource similar to 2coin.org?
That's why I ask - Is there any other resource similar to 2coin.org?
Perhaps there is a stand-alone script or software option on GitHub?
Maybe this help you https://github.com/tintinweb/ecdsa-private-key-recovery

Thank you for the advice, but It is difficult for me .
I don’t know how to work it.
Here, probably, you need to work in Python, but I do not know programming.
I need ready-made software, script or website.
Do you want to extract the private key from a transaction? possibly get the private key from a transaction but only when the same signature (k) was generated in at least two different transactions. But all these addresses are empty for a long time. Having extracted the private key from the address with different signatures for each transaction is IMPOSSIBLE.
https://bitcoin.stackexchange.com/questions/79196/how-to-find-values-n-and-k-given-r-s-and-z-in-ecdsa
https://bitcoin.stackexchange.com/questions/25814/ecdsa-signature-and-the-z-value
if you don’t know how to work with python scripts then maybe you should first learn how to work with python

Hi!! Is it easier to break an address with the public key? could you explain to me which method?

I need public key for non find number .. 64, 66 etc Grin nobody help my?
Of course, it's easier. You know the points x and y. You need to find the multiplier (the desired private key) from the generator point, that is, from key 1.

-o, --out FILE
    Append private keys to FILE, one per line

can bitcrack save adresses in file or only private keys?
to this file bitcrack record found addresses with keys.one per line.can also be called as you want -o 1out.txt, -o myrich.txt ,etc.

try to use this function, but don't see files that bitcrack record, where is it saves, in bin??
in windows it saves in the same folder where the bitcrack is located. the file is created as soon as at least 1 key is found.

-i target.txt(-i   IN)*(target.txt)a text file with your addresses, you can name it whatever you like. -continue step.txt(also can name whatever) here the program will record your progress and after restarting it will start from the place where it stopped.-continue does not work if the -r(random) flag is enabled.
