Dont think this ebook will go for a lot because it takes some preparation to be able to get the accounts to send money. Unless the methods are unique and unknown and also the securities are one of a kind. If you don't want the ebook to be saturated, write a long ebook describing cracked accounts and the whole process, provide links etc and charge for a bit more. If you just want to write a simple ebook with simple methods, it will become saturated as no one will buy it for a lot.
