if all the governments of all the world joint hands together to banned bitcoins ,then only would bitcoin can come to an end.otherwise it is not gonna happen no where soon. because of its decentralization and no technology could beat because it is the first of its kind.
Yes. If everybody dont want bitcoin anymore thats is the time i think that we wouldnt see bitcoin again. If no one wants it , it will be the start that the bitcoin will shutdown if no one wants it anymore but the fact that bitcoin has a many users now and many people wants it thats good.
