its quite possible bitcoin is really a hard cryptocurrency to predict but it is the oldest and the strongest which is being compared by the gold which is the oldest valuable stuff of earth so everyone can understand how valuable bitcoin is
No that is not possible for me becasuse if dollar will be still their since money is living for a long time and we can not change that even bitcoin is popular and bitcoin is accepted locally.. bitcoin is always good for alternative but its impossible that it can be replace we are using bitcoin because for some people they want to gamble without giving identity if its happen that dollar replace by bitcoin expect for tax fee as additional and restriction to identify your identity so gambling will close because some countries are restricted about gambling like here in my country.
