In my opinion. bitcoin is one of the characteristics of the progress of the world. because bitcoin makes it easy for people to transact so far. maybe currently only bitcoin is one of the many that will emerge in the development of the world. therefore, bitcoin deserves to be appreciated and deserves to be developed again. until the whole world can get to know bitcoin and bitcoin is progressing again. so that other people will not be left behind by the development of the world which might be progressing.
