People should use bitcoin because bitcoin can give a lot to people who do not have it all but want or deserve to have it all i think it is the best thing to let people know more about bitcoin before they actually start with it because it can go very wrong.
The only issue bitcoin is facing at a moment is that it has not reached to all people and very few people knows bitcoin and are using it and the other fact is there are no offline places where there is an option to make payment with bitcoins so if merchants starts accepting bitcoin as a payment method then more people will come to know that they can also make payments with bitcoins and looking at that they might start researching about bitcoins.
