This site is actually not fair

Look at my picture , I don't understand why I lost?

I think you lost because when you bet the price was 1 and the closing price was 1 also. It should of been a draw but I guess a draw counts as a loss.
You bet around 78000 Sats, what was your transaction fee? 10000 Sats? Seems like a huge transaction fee for such a small amount.
