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. OP maybe your question has been answered already.
