Be sure to maximize the promotion of Bitcoin to the masses, as it is quite likely that this will help it to scale.
I think i have promoted bitcoin in my own way.I used to share ideas about bitcoin with my family,relatives and even closest friends.Some of them may seem to be interested while others just ignore about it.So i just told them if you want to make sure if bitcoin is legit,you can try to make some studies about it by reading related articles available in the internet.
