Information on basically everything under the sun is public knowledge in libraries and on the Internet. That doesn't stop universities charging significant tuition for instruction.
I'm calling it a money grab because the information is such low value (you can get the same information on bitcoin.it wiki, feel free to prove me wrong), and you're trying to profit off of it.
See what I said above about libraries and universities.
Except they're offering more than just a ebook. They offer instruction, tuition, certification (diplomas), and more. You're offering a pdf with the same information from the bitcoin.it page. It's the same scummy behavior as
this ebook. hint: the "info" is the 2% cashback card they promote on their checkout page.
length doesn't imply quality or informativeness.
I didn't say it did. Actually, I tried to keep reading time short which I think is a plus.
That's funny, considering you were boasting about how "the book has several chapters" compared to the wiki page.
I can probably condense your ebook into 3 points
[...]
Feel free to prove me wrong.
I have no interest or need to prove anything to you. I'm not sure why you seem so hostile. I wrote a book which took me nontrivial time, research, and thought process and decided to put a price on the finished product. Nothing here is inconsistent with the free market. I was glad to make another good available for bitcoins.
That's just a strawman, and appeal to tone. I never said your behavior was against the free market. I'm against your shameless profiteering. How about you use your writing skills to improve the bitcoin wiki instead? It will do a lot more for the bitcoin ecosystem than a rehashed wiki article as pdf. Come to think of it, your site's autopayment script is more valuable than your ebook. Try selling that instead.
