I just tested your site with a couple of dollars, and it doesn't appear that this is a binary options site. Rather, it is a provably fair gambling site. Every time you place a prediction for up, the price on the website goes down. Every time you place a prediction for down, the price on the website goes up. Even if the price on bitcoinwisdom is going up and you place an up prediction, the price on the website will remain stable or decrease. From what I have seen, it does not appear to track the actual bitcoin price and it is misleading by saying so. If you can prove me otherwise, I would be happy to hear. At least this is under gambling, because these are not binary options.

You know what would be really interesting? If the point the bet was placed was shown in real time on the moving chart.

It would also be useful if people could set a custom payout address so they can bet from wallet services like coinbase.

The max expiry time is only 12 hours?
It's hardly to predict the direction of the price.

Would it be possible to get an expiry time of 1 or 2 hours? 30 minutes to 12 hours is a big gap.

Thanks for your reply! I just got confused with the drop-down menu that shows all the expiry times.

So I could just choose the 30 min. expiry address and send 0.10000060 for the bet to end in 60 minutes? The address doesn't really matter then?

For some of the regulars on this site.  How many seconds after you send your BTC does the bet start? Just want to find out the lag times.

Would really help if there was an online wallet.

Not offending but next time before testing something read FAQ's.It clearly says "If you send multiple addresses on one transaction only one address will be executed." here http://secondstrade.com/notice.html.
