Your dSero account is created when you submit your email.
We expect in the future to present a unified view for all sites.
Our current limit for money withdrawal is $100, but we are working on lowering the number.
We contact people as they approach the number (and intend to present a self service).
The 'lost revenue' that you see is actually your revenue, and it is summed for all of an account's sites.
The current revenues use a combination of CPM and get a boost for performance.
Best,
dSero Support
