its just about betting whether the market goes up or down in particular time frame. lets say you bet that btc's value is going up within a minute.. and if it does go up as risen within a minute, you will 80% of your bet. if you lose, you lose 100%
Maybe mean it mate like secondstrade and fortunejack have this binary bet option but this one is not trading but gambling in a short description of it easy money if you are lucky but will always ends up to losing it all if OP doesn't know to golden rule when to stop.
