https://www.packtpub.com/packt/offers/free-learningI haven't had a chance to read it yet, but their books are usually pretty good. The offer is valid for about 14 hours from the time of this post.
Please note - I have no cennectiion with the site or the book itself.
Who is Albert Szmigielski-the author of this free ebook?I`ve never heard about him.Is he one of the players in bitcoin mining or one of the bitcoin core devs?There might be some useful info for the btc newbies in this book ,but anyway,bitcoin mining isn`t ptofitable unless we use mining hardware and have cheap electricity.
By the way,i`ve never seen this packtpub.com website before.Looks interesting.
