Thanks for the vouch copy. The ebook is good and it has a useful method to earn 0.12 BTC. However, the formatting and language needs improvement. Also, if you could have a step-by-step method instead, it would be easier to read. Adding more screenshot also would help as the price you have asked is $10. The ebook should atleast have 4-5 pages and you can get them by adding more screenshots if possible.
Dint know the method is already leaks but anyways.
