I don't understand why someone will like free crypto books and as a matter of fact anything free. Free things are always shit and when it comes crypto/blockchain you should take anything as freebies because you are putting your money to invest.
Instead, the best thing is to buy some of the
best Bitcoin and blockchain books from which you can learn something and make your decision in a better. Apart from that, the book will stay with and the knowledge too that you make gained by reading a book that you have bought because bought books inspire us to read also.
It doesn't make sense, in my opinion.
Good books are good books no matter what they are free ones or paid ones.
The OP author made initiatives to help people who have not known about cryptos, and need some thing to get start with. After reading the given fee crypto currency book, if the realise the interesting things of cryptos, they will automatically find more sources to dig deeper, and paid books like those ones mentioned on your site are one of their options at that time.
The approach especially makes sense for people who come from third world, low-income nations.
- Highly appreciated your time to build up your site, and make a good collection of the best books on Bitcoin and blockchain.
- Thanks for the OP author's kindness, generosity to compose and manage the helpful topic.
Happy New year as well as happy the tenth birthday of Bitcoin!
