Yes, we paid all winnings and contest.
I'm not scammer.
don't worry about this false.



I don't know who is rollincoin.com and before bought script, i explain situation and have proof.
don't worry, I'm not scammer.
All players got all winnings!

I don't understand why you have don't believe me somehow. I find it very frustrating that you, as "Legendary" member, are trying to defend this guy. You keep repeating that this site is provably fair, even though I explained you 1 month ago(!) that this site is not provably fair. You are effectively helping his scam.




I will repeat:

This site is NOT provably fair.

The result calculation includes a timestamp but transactions don't have a fixed timestamp. Therefor the site owner can just make the timestamp a second later and generate a completely different outcome. Remember: you are not betting on a bitcoin price here. The price is only 1 part of the hash calculation resulting into a "odd/even" result.

I could copy this site's "provably fair method" and generate a losing result 100% of the time - that will still "verify" correctly.


Example

See this relatively big loss of BTC0.05 on crazybtrade.com:


Timestamp 1484500402 =    Sun Jan 15 17:13:22 2017 UTC

If you look at the transaction on blocktrail:

https://www.blocktrail.com/BTC/tx/0ea617a32f00d73d2e6d48d12adc08e60182ae12efab336dc965bbae6861f047

Received Time: Sunday, January 15th 2017, 17:13:25

Can you see, how blocktrail got this transactions a few seconds later? Do you realize there is no way for us to verify which timestamp is correct?



Let's calculate the results with those 2 different timestamps
First result of crazybtrade, SHA-256 of:
=
Since the first number is a 0 - and the bet was on "odd", the result is a loss.

Let's see what happens if we change the timestamp to the one on blocktrail (a trusted block explorer):

=
Since the first number is a 7 - and the bet was on "odd", the result is a win. So that player could have won according to the time of the trusted block explorer Blocktrail.




Note: there is no pattern between timestamp and result, every timestamp would simply generate a completely new random result. Since 0-20 second delays are normal at the bitcoin network, there are enough tries to basically guarantee a loss.




Like I said already 1+ month ago. This site is not provably fair. The site script can just cherry-pick a timestamp to make big bets lose. There is no way for us to know. And the SHA-256 result calculation will still verify according to his method.




If he really is the same scammer as that RollinCoin guy, this is an interesting development. On RollinCoin he faked the hashes to be a losing result. Since that site had a decent provably fair method - we actually could detect he was rigging the results and therefor see that he was scamming his players (and stop it by warning them.)

However with this new "provably fair calculation", "rigging the results" literally cannot be detected - since it's not provably fair in the first place. Pretty smart in a way I guess. Or maybe people like this "Legendary" member can just stop spreading the misinformation of the claim of provably fair so people might stop putting their money to this scam site.

So you're saying the information he has given so far could suggest he isn't trying to scam? With just the doubt that he may be lying of course.
Althouhg, if the scammer does still exist, they could still engineer his system and remove the money from that wallet (although the 1vs... address that he owns is not linked to any other account and does hold the most bitcoins and is what the other addresses pay to and the winnings are paid from)

Yes the site is provably fair however if you read the scam accusation thread, there is a chance this script might be linked to the same scammer that scammed many BTC in the past.

He claims to have bought the script and failed to change the wallet.dat file. Some people believed him and others didn't. The ones that didn't believe him asked him to post his Tx ID, and finally after a while he did post the TX ID, and the date matches up and everything however since he won't prove that the 0.90BTC came from his account, there is a chance he might be lying.

this is the tx. It has had 8 confirmations and still hasn't been accepted by the website?

Also, if you know a way that it can be proven both ways (like a user stated before on a different thread) it'd be good to get that solution?

EDIT: It did work. And as you can guess, as it was the biggest wager that has been made, it was held by the site.

How it work?

Verification of bet
1. The crazyBtrade.com use real time data from exchange BTCC.com (spot.btcc.com),
The buy price BTC/CNY, volume and time stamp is perfectly out of our control!

2. Provably HASH value is hash SHA256 of BTC/CNY buy price : TIMESTAMP (unix time stamp, unixtimestamp.com) : VOLUME : TXID ( bitcoin transaction id of your payment).

For example:
TIMESTAMP=1475569996
BTC/CNY buy price=4069.32
VOLUME=182820.55980000
TXID=de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175

Seed value=4069.32:1475569996:182820.55980000:de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175 (BTC/CNY:TIMESTAMP:VOLUME:TXID)
Provably HASH=
sha256(4069.32:1475569996:182820.55980000:de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175)=
1a6e1f9e27d5e8e8a2014a3c56bfd6ca975a72580aa4b1c8670bac344ca9c1f0

3. If you have choosed EVEN bet
and the first digit of Provably HASH is EVEN then you WIN 198%. Winning = bet amount X 1.98
If the first digit of Provably HASH is ODD then you LOSE.

4. If you have choosed ODD bet
and the first digit of Provably HASH is ODD then you WIN 198%. Winning = bet amount X 1.98
If the first digit of Provably HASH is EVEN then you LOSE.

You can always see the same result of sha256
(4069.32:1475569996:182820.55980000:de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175)

What about the negative trust about the provably fair thing?

Could you put your piece of mind on it and try to explain us why you are right?

It seems like too many people are claiming that something is sketchy here, would be happy if you could make a detailed post the explains everything.

Unless you do that, I doubt if someone will trust your website with more then 5 bucks.

⧉ Ignore the Negative Trust Rating, it's false, made by ☠ DarkStar_ ☠
I posted proof and toll my story, posted TX id of buying script..
No one has been deceived.
Please read my proof https://bitcointalksearch.org/topic/the-rollincoin-scammer-is-back-again-as-crazybtrade-1732739

Thanks friends!
Good luck and more wins!

First of all nobody will pay 0.9 BTC just to prove you are not a liar.

However the reason why you need to sign the message and let us verify is because we need to be absolutely sure it was your public key that paid for that 0.9 BTC transaction.

Just do what they ask and the negative feedback will be removed and your site might succeed but right now, everybody goes into this thread and see your RED negative feedback and then they run away.

Until you sign a message from the address above, everything else is empty gibberish... It's even pointless to answer. And if you answer one more time like - "read all message and get answer please..", without signed message, even I will give you red trust and I will suggest every other reader to do it.

vvv



Yes, is fact,I used my main wallet but not using now! do you able to read?

link with script where i bought (before i PM only) https://satoshibox.com/8nfrvvnvypt2qpjpvetvwb7w

Why are you writing about me? I am not scammer!
I explained my story. your proof is not valid, it is just empty words.

Try to play our game and you will understand that there is not any deceit.

or if you're so cool, buy this script and prove that I am a liar.
weak?

Ugh, how many times do I have to say this? The proof you provided is not proof, and near worthless. Paying doesn't mean it's not a scam, because if it did, Mt. Gox isn't a scam, Cryptsy isn't a scam, all those ponzis are not scams, RollinCoin and FastBitRoulette aren't scams, e.t.c.

Then you try to lure them into making a bet? LOL

Thank you for posting your TX id, I see that
1KdjwpQxUPLjaGo23tRbbSXftQVUkAekL3
is your personal address. Can you please sign a message with this address and post in this thread so we can verify that it was you who sent the 0.9BTC back in October.

You can use Bitcoin Core client to do so or you can download an old archieve copy of Brainwallet and there is an option so you can manually OFFLINE sign a message and post here your code so we can verify that its in fact you.

Because 0.9BTC are very popular amounts and you could of easily just copied someone's transaction.

I explain that i'm not scammer.
Posted proof,
Paid all winnings, contests, signature campaign, giveaway..

You can try make bets and join to contest, prize 0.1btc and you will see that this is not scam

I posted TX id, not screenshot

The fact that you bought the script doesn't mean that you are not an alt of rollin io and not a scammer.

You need to post a better proof if you want us to believe you, otherwise, the negative trust won't be deleted.
