This seems more or less like Binary Options since we are betting on whether BTC/CNY goes up or down. Just wondering if you are planning on adding some Forex pairs or some CFDs like Dow Jones 30 or Gold / Oil.

We are in need of some reliable binary options sites. Your 185% seems very fair.

wait is it 15% house edge?
can you explain 185% win to me,please
if I bet 100$ I get 285$ ,right?
or is it 185$ because otherwise it just doesn't make any sense

or is it 185$ because otherwise it just doesn't make any sense

for example:

if placed bet 100$ and win, you get 185$.

winning=bet x 1.85

for example:

if placed bet 100$ and win, you get 185$.

winning=bet x 1.85

then it should state 185% return on the bet NOT win
because when win is 185% if I bet 100$=185$ win + my stake 100$ return
and  in total it is 285$
it is misleading

No, winning is 185$. Your profit will be 85$.
Coef = 1.85 or 185%.

What do you mean its used as a random generator? The Huobi and OKCoin price for BTC / CNY is around ~5430 which is pretty close to what you have on your site. How are these quotes deteremined?

Its 15% because these are binary options and if you understand the markets you have a greater edge so it needs to be higher than  1%

i think minimum bet is high , and max bet is low 

[NLNico]

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.

Sorry but you said wrong!

because we use btcc.com ( real time data here https://spot.btcc.com/ )
timestamp is reliable, because there is fixed timestamps on transactions.

and you can check price by timestamp here

No, what I said is correct.

1. There is no way to verify at which specific point you get the trade data. Just a few milliseconds later, would result into a completly different result. I gave a pretty easy-to-understand example of this. Look at the link you gave me:

{"date":"1481768751","price":5435.7,"amount":76,"tid":"107799733"},{"date":"1481768751","price":5435.7,"amount":14,"tid":"107799734"},{"date":"1481768751","price":5435.7,"amount":4,"tid":"107799735"},{"date":"1481768751","price":5435.7,"amount":2,"tid":"107799736"},{"date":"1481768751","price":5435.7,"amount":2,"tid":"107799737"},{"date":"1481768751","price":5435.7,"amount":71,"tid":"107799738"},{"date":"1481768751","price":5435.7,"amount":333,"tid":"107799739"},{"date":"1481768751","price":5435.7,"amount":508,"tid":"107799740"},{"date":"1481768751","price":5435.7,"amount":43,"tid":"107799741"},{"date":"1481768751","price":5435.7,"amount":36,"tid":"107799742"},{"date":"1481768751","price":5435.7,"amount":8,"tid":"107799743"},{"date":"1481768751","price":5435.7,"amount":1,"tid":"107799744"},

12 trades in 1 second, all timestamp 1481768751. All of those traders affect the volume (and sometimes the price.) You can pick the volume you like and there is no way for the player to verify it. Therefor it is not provably fair.

2. There is no fixed timestamps on transactions. Each node can see a transactions at a different timestamp, because it takes time for the transactions to be relayed through the bitcoin network.
