Having looked at more English-language titles I have to wonder who Pentian's "amazing" editors are and what exactly they do. Most of the books are littered with errors (especially regarding punctuation and dialogue), and quite a few of their would-be authors clearly speak English as a second language. Many titles have raised no money whatsoever and have only a week left in which to do so. I wonder how many poorly-informed people will be tempted to put up the money themselves rather than lose the opportunity of being part of Pentian's "publishing revolution"?
Rather oddly, one of Pentian's "bestsellers" is a novel by Mary Sheldon, daughter of Sidney Sheldon. It was crowdfunded to the extent of a record-breaking $10000, but POD being what it is the book has a less than impressive Amazon ranking of 8,045,189.
ETA: I just noticed this:
Pentian works with global distributors for real bookshelves as well, and if that's where we think your book will do well, that's where it will go.
I wonder if Pentian can provide some examples of this.
In answer to the question "How much can I expect to earn from my book?"
That depends entirely on your book. If you've written the next Harry Potter or Gone Girl, the sky's the limit.

The obvious response to this is that if J K Rowling or Gillian Flynn had published with Pentian nobody would have heard of them.
It's not just the editors who seem to have an easy job at Pentian - the "marketing pros" can't be overstretched if the authors have to "self-promote to the max", and although quite a few of the covers aren't bad they're no better than stuff I've seen on Fiverr.
Finally, Pentian claims to be "the crowdfunding platform that allows every reader to become a publisher". But if Pentian handles "allocation and management of ISBN" the reader (don't they mean "writer"?) isn't the publisher. If you don't own the ISBN you haven't self-published.
