Before I had 0.0009 and now I have 0.002 it is taking more
You do realize 0.002 is larger than 0.0009, right?
And Brave wouldn’t take such a small amount. The auto-contribute is typically 1 BAT. So doesn’t sound like you have that going on.
In any case, would help if you give more information on where you’re looking and what you think you’re seeing. Unless you just were seeing numbers wrong and thinking somehow 0.0009 was larger than 0.002.
