Brave points keeps on going away

my brave point were at 2.14 usd then 2.08

If you are talking about the dollar amount that is because the price of BAT has been decreasing these past hours. BAT is currently priced at 0.66 cents according to Coinbase. 24 hours ago it was valued at 0.74cents

o thanks i thought the bug came again

If it was decreased BAT then yes that would be a concern, however, fluctuations in the USD value of estimated earnings is purely on what the price of BAT is currently at.
