1  Economy / Scam Accusations / [Cryptoplay.io] CRYPTOPLAY CASINO SCAM - RIGGED FAIRNESS on: October 17, 2022, 09:39:58 PM
What happened::
Cryptoplay.io casino has rigged fairness and changed hashed server seed. My friend made 10 deposits to hit keno 500x on the same pattern on a new seed(over 35000 rolls/nonce) for days but this seed was the definition of "bad luck" before we exposed how Cryptoplay changed game results. He took screenshots at different nonces to save Hashed Server Seed to verify fairness after hitting 500x on this pattern. Over 35k nonce, he gave up to deposit and decided to play with the lowest possible bets to see how far the loss streak can go. He hits 500x on this pattern and decided to verify the seed on the PHP verifier.

He changes the seed to see the server seed that must be used to verify bets on that seed but the given hashed server seed doesn't match with the Hashed Server Seed on his saved screenshots. After checking different screenshots and comparing with the Hashed Server Seed given by scammers aka Cryptoplay casino, the Hashed Server Seeds are completely different:

The original Hashed Server Seed
Code:
fc86f14b39cb68ef55a9c0f8133494fa5f340a1b17b5af0d285af6247507815a


And Hashed Server Seed on the bet after changing seed to verify previous one:
Code:
4d15ef41be8c0d1ac427924e71bd249d5c44587d95262b54fa3127a6321c1203


Same nonce, same client seed different Hashed Server Seeds mean scammers have changed Server Seed.
We have screenshots of other bets, you can check below links.

Important note: The 'Server Seed hash' won't be used for the computation but it acts as an assurance that they won't change the server seed to manipulate the result.
Experienced users can confirm why Hashed Server Seed is important to save for verifying bets so Casino didn't manipulate the game result after the user makes a new seed. As you can see on the saved screenshots, Hashed server Seeds are different on the same bets of this seed, clearly scam. Cryptoplay scammed my friend and he lost $700 on this seed.


Support clearly ignores my questions and keeps repeating  to check modified Server Seed "Go check the bets on the PHP verifier and send us screenshots". First Mario tried to "explain" why there are different Hashed Server Seeds on the same bet, he first tried to close case by simply telling it is "display error" but I told him I have more than 3 screenshots taken on different nonces/time. And on his second attempt to explain: Mario:
Code:
"Server seed hash is a warranty that can be applied to max 1 bet", "It would only work for one bet, this is why the hashed seed is a warranty only for the first bet, otherwise it proves nothing"
So logically it means, hashed server seeds change per bet/nonce?! The worst part is Sam(manager) came to chat as manager but he refused to answer any of my questions, he didn't explain why the Hashed Server Seeds are not same on same bet/nonce. Sam:
Code:
"My colleague Mario explained it to you in the most comprehensible way possible"
I shouldn't expect more from the support team of a Cryptoplay.io scam casino, none of my questions are answered and they tried to make it more complicated on provably fairness subject. They simply rigged the game results to scam users and get caught.




Cryptoplay(Cryptoplay.io) is a scam casino that manipulated game results, and rigged seeds to scam users!

2  Alternate cryptocurrencies / Service Discussion (Altcoins) / Exchanging altcoins for Gift card on: March 18, 2020, 11:45:55 PM
Can someone please suggest a good marketplace for swapping the altcoins and purchase gift cards? I mainly look for Amazon, eBay, Target gift cards. Only Bitify and Bitrefill have this option but the rates are lower than average market prices. Coinsbee.com and coincards.com also have the altcoins section for buying gift cards but there is no review site to check the quality of service. If someone has a suggestion, don't hesitate to share your experience.
3  Alternate cryptocurrencies / Altcoin Discussion / Insider trading groups in crypto on: March 18, 2020, 11:10:46 PM
I have seen many fake and legit insider new websites on DeepWeb but have never interested to join due to legal reasons. First, everyone is aware of such groups and from an ethical perspective, joining these groups will not add anything for the average trader. Big boys use the special algorithms for finding the weakness and they make their own "bias" in the market with different speculative-manipulative moves. For example, you can easily find a stock share insider group but joining them requires to be an average whale. Paying for subscription or bribe doesn't give you a chance to exploring the latest updates/news. Only having access to early reports and sharing it will make raise your account to the full level. Do you think there are such types of crypto insider trading groups in the dark side of the internet?
4  Economy / Scam Accusations / [Warning] Phishing Mixing Website on: March 18, 2020, 08:07:10 PM
What happened:
The newbie user has opened a new thread with a fake mixing website and he offers 0.005BTC per review. The phishing link is inserted in the text and the collected info will be used for data mining.

Scammers Profile Link: https://bitcointalk.org/index.php?action=profile;u=2782997


Reference Link
: https://bitcointalk.org/index.php?topic=5233798.0

Proofs
:





I sent an email to Mixtum's official mail address but the mail has been returned to the sender. The mail address of Mixtum doesn't work and it is a bit suspicious why the scam attempt was first done with the original URL of Mixtum. Maybe the attacker has gained access to the site and later decided to change the inserted link to a phishing site for registering new users. I contacted the site owner and asked the same questions there.

Since the thread is inactive and there is no update after the last post, I tried to contact the official mail of [banned mixer]. The sent mail was returned to the sender and it looks like the service mail is not used for a long time. I checked the other mail addresses under the same mail service provider and everything is ok except mixtum_mixer@protonmail.com. Please confirm both clearnet and onion mixing service work normally. There is no alternative option to contact with developers for confirming such cases.



Will update later.

6  Alternate cryptocurrencies / Speculation (Altcoins) / Fed’s QE Program and altcoins on: March 17, 2020, 07:03:32 PM
The FED is a private institution and this fact is confirmed several times by independent economists. The last enormous program of quantitative easing decision will affect the BTC prices positively and the market will have a recovery chance with this push. The correlation factor let me to think about the same effective rate over the BTC correlated markets. So speculators prefer to wait for settled dust and buy the dip on the altcoins along with BTC. What is your approach?
7  Alternate cryptocurrencies / Altcoin Discussion / Reverse Martingale strategy for trading altcoins in bull market on: March 11, 2020, 11:35:46 PM
Suppose the trader has $10k and he wants to buy an LTC. After the negative news, the price of LTC drops and 20% of the initial balance melts. The trader will have revenge emotions and will want to add more LTC position on leveraged altcoins trading platforms. For the first chain of the loss cycle, 1:2 leverage is enough to cover the loss with a first winning trade. What if the market goes against the new trade and hits stop loss? The trader loses 40% of the balance. The best idea is to avoid the martingale strategy in the bear market but the leverage tool with smart money management can be the best tool for increasing ROI. For example, the same trader opens reverse trades in parallel space and for whatever reason, the price goes up. In this case, the trader will have $12k worth of LTC and opening a new trade with borrowing from the broker($2k profit=margin), the sequence will bring the max profitability.

P.S: The margin trading is dangerous for inexperienced traders and stay away if you have no idea what you are doing. Not everyone can handle such expensive lessons. Please do your own research and calculate the risks in case of being another side of the trend.
8  Alternate cryptocurrencies / Marketplace (Altcoins) / [WTS] INS for XNS on: March 11, 2020, 10:52:02 PM
Have around 1039 INS but I don't have time to wait for the swap(+1). If someone has a good offer, you can pm me. There are a lot of online article sources(information) for understanding the terms and conditions of the INS swap to XNS, everything is crystal clear for the average crypto user. The swap rate and other details can be found here, pls read before asking the same questions. For the negotiation, you can send me your offer.
9  Alternate cryptocurrencies / Altcoin Discussion / Stolen recovery seeds by malicious Chrome extensions. on: March 10, 2020, 11:58:53 PM
Malicious Ledger Live app is used for stealing the recovery seed after connecting the hardware wallet device. The well-designed Chrome extension tries to trick users into thinking this is the original version of the Ledger Live app while the app, in reality, collects and sends the user's Ledger seed phrase to a Google Form. The google ADS are heavily used for advertising the extension and 120 users have downloaded it. Be careful with third-party apps and never try the risky apps from unknown sources. Source for rest of research.
10  Alternate cryptocurrencies / Service Discussion (Altcoins) / Advantage of MyCrytpo app compared to MyEtherWallet on: March 10, 2020, 08:46:14 PM
About MyCrypto:
Quote
MyCrypto is an open-source, client-side tool for generating ether wallets, handling ERC-20 tokens, and interacting with the blockchain more easily. Developed by and for the community since 2015, we’re focused on building awesome products that put the power in people’s hands.

About MEW:
Quote
MyEtherWallet - please, call us MEW - puts the Ethereum blockchain at your fingertips. We are a team of crypto-enthusiasts dedicated to bring you the most secure, most intuitive, and dare we say prettiest way to manage your ETH and ERC20 tokens. We're always here to help, and we're never giving away ETH.

Way back to 2018, MyCrypto was nothing more than a fork of the existing MyEtherWallet, many things had been changed since the mentioned time. Both wallets are well-known wallets for storing ETH and ERC20 tokens. I prefer to use the MyCrypto desktop app after the latest updates on Myetherwallet site, there is no option to create a new temporary ETH wallet with the private key. The whole process can go up to 5-minute per single ETH address because of verifying seed or mnemonic phrase. The Mycrypto app made it simple and the KISS(keep it simple stupid) rule is my first criteria for saving time. Just using a random password without downloading the JSON file, it is simply easy to copy and save the private key of the new ETH wallet address.
11  Alternate cryptocurrencies / Speculation (Altcoins) / Insolar MainNet and XNS price speculation on: March 09, 2020, 11:16:25 AM
You can read here about the INS to XNS swap. The last announcement about the calculation method after mainnet launch tempted the investors to buy a new batch of XNS. Etherscan and other ERC20 token explorers still indicate the current price of XNS coin for the INS tokens in ETH wallets. The swap will be distributed daily and the minimum required time is around 3 years. Btw, everyone can use this Excel formula as Insolar XNS vesting calculator. What is your price prediction after 3 years? How the latest news will affect development? Does it worth to invest further in this project or invest proportionally?

Was selling few btc, and posted on a thread of a guy who was buying. Got the PM later that he wanted to buy, I insisted on escrow, he suggested Yankee (Bitinstant), good ols user and I accepted.

Only when I sent coins to supposed escrow I noticed that account I sent to was completely new and had dot after Yankee, while supposed segvec I was trading with is actualy seqvec.

5 BTC gone to wind due to my stupidity.

So, be careful and avoid doing the same mistake.
