I put this on "Gambling," but after a request to put this in "Goods" or another Marketplace category, I decided, what the heck. Previous topic below.
https://bitcointalk.org/index.php?topic=197060People take works that have fallen out of copyright and sell them, like old movies, William Shakespeare's plays, and so on, so I decided to do something similar.
I took a bunch of public domain books I found on the internet, concealed their titles to make them surprise books, and uploaded them onto CoinUploads. You pay 2 dollars worth of Bitcoins for each book. You don't get any money in return, but the concept is, if you discover a book that enjoyable for you, you win a bet, whereas if you discover a book that's not enjoyable, you lose a bet.
A version of a public domain work can be copyrighted, but I never uploaded any books from any organization that said their versions of public domain books were copyrighted.
There's millions of public domain books out there, and it's probably impossible to know about millions of anything. So you'll likely find books that you would never have known about otherwise. It might be a book you wouldn't normally give much attention to otherwise, but maybe in the best case, you're pleasantly surprised at the information you didn't know would be interesting to you. Paying 2 dollars and seeing what the book is and has in it, would that be fun? Are you willing to do that?
I tried to have books that represent at least a fairly wide range of interests and, and I think they're more obscure books, so it's likely you'll discover a book you never heard of. All books are in PDF format.
