ODD - EVEN win 198% | Provably | House edge 1%

[DarkStar_]

I don't use private key..
If will be make easy how you said, rollincoin will withdraw my money! But he have not access for my blockchain node.

Go to your bitcoind. Run the command dumpprivkey 1vsUrQQq9UaNycnpbPKRkHSe7th4n8R3k, and you will get your private key. Changing your password does nothing.

Let's say I own address 1L7odHB17KgZZQUn3Smt6fz7Pkz7ecPoAn. Like an idiot, I give my friend the private key below:

Code:

L39HmyP4RYK4chzmJUW2zaF47CA8H2tTTq5P6juE8V1E5mSkBy17

I could use a 500 character password on my bitcoind for the address, my friend could still use the address/spend my funds, without needing a password or access to my node.

They said about scam...but they don't placed bets.. This is trolling my game.

One does not need to be scammed to call foul. It we did, pretty much every scam in the BTCitcoin world would be successful, and we don't want that happening.

I posted all proof that bought script and i don't know who is rolloncoin in past.. i posted link where i bought script and contact for install bitcoin node.. after i changed all passwords. I have all proof! also i paid all winnings and contest.

You might have changed all your passwords (which you didn't, unless you don't count for forum account), but you still hold 1 BTC+ in addresses you know are compromised by "RollinCoin". If you don't know (or aren't that person), why would you trust them with 1 BTC, knowing they can steal it without any risks really, and have been warned by many people?

btw, I like your proof that DarkStar_ = DarkDays

Why? I changed passwords for hosting VPS and mysql DB. and no one have not access to this wallet!

Could you buy this site? after clear red trust..

Yes you changed that but why didn't you change the bitcoin addresses why did you leave them as is?

The reason you got caught is because you played many fake bets to get your sites to show volume but the main address which is:
1vsUrQQq9UaNycnpbPKRkHSe7th4n8R3k

Is basically in the exact same wallet from the exact same computer from the exact same bitcoin core belonging to RollinCoin admin.

So every deposit that you get, you don't have the private key for ?


I also don't think you can sell this gaming site since you "bought" the script and aren't the original programmer for it.

Caught? No one fake bets here! All wallet address are players!

EVERY BITCON ADDRESS HAS A PRIVATE KEY.
It can be controlled so easily that if I put 1BTC in a wallet address and posted the private key here - the money would be gone within 5 minutes!
The private key is what is needed to control th bitcoin addresses. Wehn you make a paper wallet you essentially print the private key. You then just need to scan it to transfer those bitcoin to come back online.

IF the scammer has your private key, they can wait for you to get more money and then merely deactivate your bitcoin address by scanning the private key.

If every bitcoin address has private key.. this mean that he has not private key because i created some new addresses for betting and he has private key for old addresses.

Remember, it's not provably fair, so there's a very real possibility that you are getting cheated.

Really?

don't post your shitty message here, please.

Our game is provably fair! if our system is not provably fair then famous exchange BTCC is not provably fair too.. and all dice game is not provably fair too..

[DarkDays]

I just want to emphasize that this site is not provably fair.

It also has indeed a 7.5% house edge, which is relatively high for a simple dice-like game (but covers the mining fee too I guess?)



Why is this site not provably fair?

It uses timestamp and unverifiable third-party data for the bet results. It is very easy for the site to slightly change this data (just a few milliseconds later) to make you lose.



Example

Imagine I am betting EVEN. The bet result is: sha256(BTC/CNY:TIMESTAMP:VOLUME:TXID) Let's say the site picks the following input data:

BTC/CNY: 5436.23
TIMESTAMP: 1481781996
VOLUME: 957326.6386
TXID: de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175

This results into: ebbc2a4ec2ec8b82336cb8b51f32dd3d523f7bac5da76bac0629123e44ac2fea

As you can see, the first digit is EVEN so I should win.



Now the problem is, BTCC has many many trades PER SECOND. So if I win with this input data, it is very easy to just get the trade data from a few milli seconds later. Because a few milliseconds later, another trade is done - making the BTC/CNY price and VOLUME different. This results into a completely different result. For example, the data of a few milliseconds later would result into:

BTC/CNY: 5436.24
TIMESTAMP: 1481781996
VOLUME: 957326.7386
TXID: de1f78ed0e2fdb557458a4af1aecf17d73b06df8ed51cd0d14919dcf995b4175

This results into: 55f0fc73a8a239662184f0873dfe93574591f4542ad72b3f66617f3e877294a7

So by just getting the input data of a few milliseconds later, they can make me lose.


That's why you cannot use unverifiable third-party data like this. Even the timestamp is unreliable, because there is no fixed timestamps on transactions, so it's very easy to remove or add 1 second.




I am not claiming the site owner is doing this. But calling this site "provably fair" is just not correct. If you want to make your game provably fair, you should look how other on-chain games do it, like luckybit.

This wrong! you can check price on btcc exchange and verify your bet and price.
This easy!

[chixka000]

I highly suggest locking this thread out. There is no point in discussing this things here. If the crazybtrade would be selling it then there is really no more point to continue arguing in this thread. Scam queries were made in the proper section.

Exactly. 

He doesn't know what a private key is.

He doesn't know what double spending is.

He's just wantonly stealing people's money.

Yes either he is a scammer or he has no clue how bitcoin works. So if we assume he is not a scammer. All his profits are going to a wallet that is not his and he doesn't have the private key for.

That and almost every other better on his site is always a double spender. I agree with the other post this thread should be locked until he provides evidence that he is not a scammer which is highly unlikely at the moment.

I explained 1000 times that i'm not scammer!

how many placed bets on my site?

[GoogleCoupons]

They still complain about you are a scammer?
Don't they have a life??

The current website that he is running hasn't scammed anyone yet. But upon much investigation we have discovered that one of the deposit addresses on his new website is linked to the same wallet as a previous scam site.

We questioned him on this and his responce is that he is not that scammer but he simply bought a website script and forgot to change a few fields like the BTC address. We didnt believe him but we figured if he can prove that he bought it and isn't the old admin then he is not a scammer. So he said he paid 0.9BTC but couldn't prove it. Because the TX id he posted there is no idea if it belongs to him or not because he refuses to get the message signed.

With all due my respect, I actually want to make " Scam Accusations " for crazybtrade. Without further ado here may already proven REFERENCE 

Is not scam. You tried cheat us.
Use double spends and transactions spends an input which is unconfirmed.

....

There's not hole for double spend, I've enough fee for every transaction 

...
Your 1 bet is really, 9 bets is fake.
after my post, he confirmed transaction but he want cheat our game.. our game not pay winnings to cheater
...

In fact you got my money 

Looks like Crazy stole .02BTC from him by claiming that he double spent the money sent...all of those transactions, by the way, have over 10,000 confirmations by now.
