I have seen many offering free ebooks or costing for the ebooks.I do not know much about them. do they really worth of buying or simply scammers. Because mostly i could see only scammers in this field where in the book containing no useful information. And though if it contains much, will we be able to earn something out of it.
Really depends who is the author of the book. The author of " Day Job Killer" has also created 2-3 other e-books, plus I think a software which were all hot. But most e-books are filled with the same e-book, that you could find for free.
Yeah, some of them have great ideas - but some are just full of spam. If you find some by reputable authors, then go for it
If the ebook is explaining the basics of things... have a read There are some paid ebooks that have no quality what so ever, which can be worse than free ebooks at times.
