Reading is not useful to only leaders, everybody must read to be enlightened. It is also important to state that it is not all books or information that is truly helpful. That is why we must always verify and meditate on what we have read from books. One of the problems most countries are facing is that their leaders are technologically, economically and politically backward because they don't study. They govern their country and make policies based on outdated knowledge that might not be relevant currently. That why most government are banning or restricting the use of Bitcoin because they lack requisite knowledge about its operations and benefits.
