Hands down this is the best bitcoin binary options site!

The reward is better than other sites 80-90% return on all my trades (1~4min: 180%,5~29min: 185%,30~720min: 190%), haven't experienced any delay or price manipulation, and they allow trade durations from 1-720 minutes. Most other Binary sites offer only 60 seconds which really is more gambling than trading. Anyways, for btc/usd everything is easy just select a time duration from the drop down menu then click up or down and send to the address.

Forex/currency/futures/commodities are a bit more tricky but still easy enough just add a 3 digit number to the end of your payment for example 0.25111005 is five minutes 0.25111060 is 1 hour etc.

As for the dice portion of secondstrade I don't play but it looks nice. You really should read the how to page in order to understand how everything works before playing though.

AAA+ site
