It will increase further as you pay for bills.
For new account they always start low, check inside the settings if you can increase the threshold yourself. If not reach their support, after few completed payment you can ask to increase it
I'm not sure about that, the last account I started last year also was around 2$... Just start advertising, they will bill you every 2$ and this will quickly start increasing... But every new account means lots and lots of small amounts charged to your CC... I guess the big FB is scared of any new user not paying his bills.. It does not really matter (apart from the fact your accountant might not like it)But a month ago it was starting with 20$ am i right ? what happened now ?
