1  Alternate cryptocurrencies / Altcoin Discussion / How to Retrieve an ETH keypair from HEX on: September 24, 2017, 09:51:18 AM
I know that there is a way to generate a bitcoin keypair programmatically.
Is there a way to retrieve the ETH address from existing 64bit HEX string (private key) like this:

Any information would be useful. Thank you.
2  Alternate cryptocurrencies / Marketplace (Altcoins) / 0.01ETH needed for an hour on: September 23, 2017, 04:52:44 AM
Hi, I purchased some CSNO tokens, but since I am newbie at ETH I didn't know I need 0.01ETH to send it to the exchange.
Anyway - exchanging btc to ETH, and sending it to my wallet would cost another 0.01ETH, so I assume it is better to ask for a small loan.
Will repay this with 15% fee today.

4  Bitcoin / Development & Technical Discussion / Question - Is there a way to programmatically check if wallet exists in chain on: April 15, 2017, 04:09:04 PM
Hi guys,

Sorry for the dumb question but I am writing a software and I am wondering if there is a way in C# or Java to check if a wallet exists in the Network already, or the date of creation of a wallet?

Thanks in advance.

6  Economy / Trading Discussion / COIN ETF - Effect on Bitcoin on: March 09, 2017, 03:18:16 AM

As we all know the final decision of SEC regarding the Winklevoss Bitcoin ETF (COIN).
What do you think is going to happen if it does get listed on Nasdaq?
Price movements? More Regulation?

I personally think that in the long run prices will skyrocket.
7  Economy / Trading Discussion / [IDEA] Blockchain 51% Commission on: March 01, 2017, 06:48:18 AM
Hi bitcoiners,

Commission might sound weird but in this case it's appropriate.
I don't know about you, but I've been scammed out of bitcoins many times during the years.
I've lost more than 10,000 EUR for the last 5 years to scammers - either theft or transaction reversals.
Every time I start to get ahead someone steals or reverses transactions with me and I end up losing my hard earned bitcoins or cash, depending on the transaction.

This is because scammers think that Bitcoin is irreversible.
Actually - it is! With a 51% attack - requiring a lot of hash power.

I say we, the bitcointalk users, speak in person with representatives from blockchain to unite force and with enough evidence be able to get the coins money back from thieves and back to the rightful owners.

I propose a commission to be created from moderators, notable users, scam victims here and to investigate every payment reversal. If enough evidence is found - we just inform blockchain, provide details to them and they do the rest. If necessary reverse/downgrade the blockchain in large fraud cases!

I am tired of people stealing and getting away with it. Paypal, Skrill and various payment methods are doing it just because they can, and they're never held liable.
The only difference is that our commission is going to retrieve bitcoins back from scammers after solid evidence are provided.

People deserve to get back their stolen money, that they've mined or worked for, and just because bitcoin is not centralized, doesn't mean that we have to sit and take this abuse!
8  Economy / Goods / [WTS]Lumii Digita 600W on: February 23, 2017, 07:16:21 PM
I am trying to sell a digital ballast - Lumii digita. Slightly used - for around 4 mths.
With box and 220v cable - EU version.
Price on is around 60GBP so I assume 45 quid would be a fine price (preev).
I could accept reasonable offers.

How it should work - coins placed in escrow.
I ship. When you receive - you release.

Post here if anyone interested.
9  Economy / Scam Accusations / [SCAM] [Unresolved] Skrill Reported to Europol and IMF - time to face charges on: February 20, 2017, 06:57:54 PM
Issue is that one of their Sr. Fraud Analysts knows me and has a grudge over me. And he's placed me in a weird list where all my trasactions are monitored.
Users DianeT510, meinfreil and Zenyatta19 have sent payments to me, I released the bitcoins immediately and they went to complain to Skrill to reverse the Payments. DianeT510 even replied to me that she didn't request a refund. Sent me screenshots of her Skrill, but still those bastards reversed my payments.

I am filed a lawsuit against Skrill today. They disabled my account, they lied on record that I would be able to withdraw my money, then they reversed all. And charged me 45EUR fee for it... I have nothing left now.
I am also filing criminal charges tomorrow, because what they did is fraud.

I will keep you updated. I will make a big noise about this.

I lost more than 500EUR - and I have receipts from a BITCOIN ATM and all - showing recipient address on Paxful.
I also shown them the transaction chat logs. And people confirming they didn't want a refund.

The arrogance of their personnel is going to cost them JAIL TIME as well as brutal fines.
All the big dogs have been alerted. I expect action within a few weeks.

EDIT: FYI - today 3 people from AW-Tronics were arrested because they lied to the DoJ in their documents for selling parts in Syria. 1 of them from Bulgaria (where Skrill's Security Team is located).
Don't forget that Trump is stumping hard on the Arabs and Money Laundering from their countries. This is going to be heavy hit on S(hit)krill

Write here or PM. No ICQ and Skype deals, no "you send first" crap.

EDIT: FYI - I've never dealt with anyone in the forum.
And according to the forum I'm trusted. My red tags stick. But I always tag scammers only. Never honest traders.

12  Economy / Trading Discussion / Payment methods which are hard to reverse on: February 06, 2017, 07:48:29 PM

i've been using Skrill and Neteller for some time, but they keep blocking my account after each payment I receive which kills the incentive to continue using their services
do you happen to know a similar service, which is hard to reverse
i want to trade successfully for high volume on exchanges but i'm afraid that my cash will be blocked for an undisclosed term, and that's not fun

i want to be able to do daily exchanges
i got the coins, but it's just not fair how many people steal accounts, or use other people's accounts and I end up paying for it from my pocket
13  Economy / Scam Accusations / cryptodevil is assisting a criminal to steal 480 bitcoins on: January 31, 2017, 08:34:29 AM
The forum member cryptodevil for some unknown reason is defending Steven009, trying to get an account back from BTC-e.

In short:
1. The user Steven009 claims that he lost the Gmail, the skype and the wallet used to fund the account;
2. He also claims that he is unable to get back the Gmail, skype and wallet; He also changed the account email address which was why it was blocked!
3. He sent photoshopped documents, showing a wallet and no real evidence that he's the real owner;
4. He refuses to send notarized documents, or go to a verification center. The provided from this user are only screenshots and scanned documents, which could have been bought online;
5. The amount is 480BTC;
6. Instead of really trying to solve his problem he came here pointing finger at BTC-e;
7. He also was unable to send a small transaction from the originating wallet, which "he's lost control of";
8. He waited for 13 months before acting.

None of the above makes sense.

One also asks a few simple questions:
What if it was my money? Would I stand by, waiting or would I go to get my coins?

One also wonders:
Why most users here get grilled for 50$, but we assist someone that has no valid proof with getting 480BTC from one of the oldest exchanges, that Operates since 2011?

Explain yourself cryptodevil - why are you so vigorously defending a guy with no proof of anything?

As I said in the thread that Steven009 started - this is a crime, and if you don't want to be in the middle of it - better start explaining.

Again - forum rank means nothing to the police, which will be alerted if you support those fraud attempts.

Since you're claiming to be the Police here - you're in the hot seat, buddy!

Who am I you ask? Why is my tag red, you ask?
Please take a look at the comment that cryptodevil placed, and also read why:

Basically I am red tagged because I am asking valid, sensitive questions.

I think that cryptodevil is either Steven009, or that he's been promised a percentage of the spoils.

PS: Gmail cannot be recovered, because on registration you have to put a phone number. And since Steven009 is not the real owner of the Gmail - he doesn't have the phone number to recover it! Google doesn't delete accounts. Anyone with a brain knows that. They disable it upon request and are able to reinstate in the matter of seconds - it's a huge domain based environment (i was a sysAdmin for a while).
And the scammer needs email confirmation, in order to withdraw the bitcoins.

15  Economy / Exchanges / [SECURITY] How to spot a scammer on Paxful on: October 23, 2016, 08:16:10 AM
Hello Traders,

This is a topic that i think would be very useful to many of us, because it reveals how to protect yourself on Paxful.
I've been dealing coins on their platform for a few days, and to be honest, it's very hard to get scammed, unless you want to be.


Typical Scams

Case 1 - The Password Change Attempt
1. You click on a SELL offer (for an online payment provider such as PayPal);
2. An escrow is opened, and you provide the PayPal email to the scammer;
3. Then they ask you to send them a verification code, that they would "send to your phone" (if they're unable to do so - to your email);
4. They send you a password change email or phone message;
5. If you provide the code, and have no 2FA, they cancel the deal, access your account and steal your coins.

Case 2 - The Moderator Advising you to Release Coins
1. A scammer buys (places in escrow your coins);
2. Then they ask you for personal data, such as your email or phone number;

subcase a)
i. There they send you an email from (ANYONE CAN DO THAT - EXAMPLE LINK);
ii. In the email in very bad English they try to convince you that they've blocked the user, and to release the bitcoins, which they would add to your balance manually within 15 minutes;
iii. You seeing that it's sent from the proper mail address do as advised and release the coins, not realizing that it was all a scam.

subcase b)
i. They send you message in the Escrow chat claiming to be a Moderator (MODERATORS POSTS ON PAXFUL ARE ALWAYS IN LIGHT BLUE HIGHLIGHTS!), or a security team member, claiming that you're a victim of a coin-locker, and you have to release the bitcoins which they would add to your wallet later by hand;
ii. You seeing the message has a title Moderator do as advised and release the coins, not realizing that it was all a scam.

Case 3 - Marking Payment as Made, before the buyer paid
1. A guy responds to a BUY offer that you posted;
2. He asks you for an email address and claims that he's made payment;
3. They mark it as Payment Complete and ask you to release the bitcoins;
4. You stumbled from the enormous profit, don't think to check it first, and release - forgetting about seeing your cash again.

Case 4 - Asking for a loan
1. A guy responds to your offer and buys (holds in escrow) a small portion of your coins;
2. Then he politely asks you if you could loan him 20$ (for instance) and they would pay you back 125% in a few hours;
3. The profile that made the request has a few green + ratings (easy to fake) and you do as advised - losing the coins to a scammer.

NB: Those cases might be intertwined. It's not said that a scammer would use just one, but they might incorporate parts of any of them into their scam attempts.


1. Before you even fund your account - enable 2FA (SMS or Google Authenticator) for ALL available options through the security tab in your profile (link);
2. Never release bitcoins from escrow, if you have not received the payment! EVER!
3. Do not be fooled by 100% green reputation. Always do your due diligence and check the users that left the reps. If they are reputable with more than 100 deals and more than 10BTCs traded - then you have a legit trader.
4. If you receive a suspicious looking email from - bad English, bad grammar, etc - try to reply to it! If you get a mail-delivery-subsystem message (link) then the message was not sent from the original mailbox, it just used an mx record to look like it was.
5. Never click on links received in the emails from point 4;
6. When posting a Trade, always require the user to at least has verified phone number/email address, 10+ BTC trades, and to be trusted (there is an option for that)!

1. Case 1:
a) Never use the same email address for your payment method and Paxful. Also - never provide your Paxful email;
b) Never provide a phone number linked to your Paxful account or your payment method;
c) Try reasoning with the guy - just tell them that you did not request a security code (as it's supposed to be for your security) and it's better to cancel and not lose your time.

2. Case 2:
c) save all data - make screenshots of the conversation + forward the scam email to from your paxful email and also send it to the chat support with the attachmens (even if they're offline);
d) report the user through the report button.

3. Case 3:
a) Look at Case 2a)
b) Look at Case 2b)
d) Look at Case 2c)
d) Look at Case 2d)

4. Case 4 - Just use your head. Don't send money to people you don't know with the expectation that you would ever see it back.

Final thoughts:
It struck me that i read a forum full of people thinking that Paxful have a Team Member named Marcos, with bad English, who advised them to release coins. That's why I wrote this guide.
I actually corresponded with Arthur (the owner/founder) of Paxful and his English is perfect. Even if there is a Marco(s) in Paxful it is definitely not the guy that sends you those scam emails.
Just think people. This is how PayPal accounts and credit cards get stolen!

*Note - I am not in any way affiliated with Paxful, nor am I their employee!
16  Economy / Currency exchange / [WTS] xBT/BTC/bitcoin to Skrill / Neteller / Perfect Money - Escrow - 10% fee on: October 13, 2016, 08:13:59 AM
Hello Xchangers

I want to exchange bitcoins for Skrill / Neteller / Perfect Money (one of these). I charge 10% fee.

How I like to Do busines?:
I like fast transactions:
1. We establish a deal;
2. We find an Escrow Service (ES);
3. I fund it;
4. Escrow Provider (EP) confirms to you that escrow is funded;
5. You pay for the bitcoin through one of the payment methods;
6. I advise the EP to release Escrow;
7. I Pay the ES fees.

I don't think this whole process should take more than 1 hr.

PayPal is possible too, only through localbitcoins and if my rules are met (and they're not easy to follow).

Escrow is a Must.
No skype deals. No ifs, ands or buts

Why I prefer Skrill / Neteller / PM than PayPal? Not only because of the so called Buyer Protection, but also their continuously changing limits and policies, that might block my cash for a long time, or hold me liable for a crime i didn't commit.

For Escrow - Id use TomatoCage or monbux, whoever responds to my messages. Please note, that no reputable escrow has replied to PayPal related deals. So... yeah... that.  Grin
17  Economy / Currency exchange / Exchanging Bitcoins for PayPal/Skrill/Neteller/Perfect Money - 10% fee on: October 04, 2016, 08:12:18 AM
No skype deals. No ifs ands and buts. (some pun intended)

Read title. I exchange Bitcoin for PayPal/Skrill/Neteller/Perfect Money

Premium - 10%.

All paypal payments must be split into 4 parts and the following text must be added to each payment's memo line:

Intangible service #{provided by me}. Non-refundable. Payment X/4

Where X is 1, 2, 3 or 4.

EDIT: Also, an email sent to me would be required from the PayPal registered email that you approve the transaction, and that you're satisfied with the service that you received.

We shake it on a 100$ deal:
Intangible service #0001/4X16. Non-refundable. Payment 1/4 -25$
Intangible service #0001/4X16. Non-refundable. Payment 2/4 -25$
Intangible service #0001/4X16. Non-refundable. Payment 3/4 -25$
Intangible service #0001/4X16. Non-refundable. Payment 4/4 -25$

If the above rules are not met - I will refund you, and the deal will be canceled until you comply.
There is too much chargeback fraud going on through PayPal
