why do you have to be frustrated with what you can't control, you can't make everyone have the understanding and belief in bitcoin as you have now, just let people open their hearts to bitcoin slowly even though it will take years to come.  the current generation, the majority of whom still close their hearts to bitcoin, will be replaced by a generation that certainly has a more modern rationale, so actually giving the bitcoin doctrine must start from small children ^{(you can start from the children around you maybe)}, slowly but surely people will have great curiosity about bitcoin.
