I think the best way that Bitcoin can be spread is by doing public demonstrations, and giving free BTC small amounts around 0.02 to those who take an interest.
The only people who could do this is the ones who brought when the price was incredibly cheap and are now BTC rich, this will be a great way to give back to the community and intern help raise BTC popularity and usage and of course making it widespread.
This is demonstrated beautifully in this documentary :

giving away $9 just so people can see it move from your wallet to their newly made wallet, alone is futile and expensive.
what you need to do is find local shops in your area to accept bitcoin. or encourage new ones. and then use maybe just a couple $ to let the person you gave that funds to, buy a coffee or a snack.
the reason is.
i can make an app that sends bullshit value from one phone to another.. in milliseconds.. but if that person cant do anything with bullshit coin.. you might as well threw a brown shirt button on the street (looks like a penny from a distance) and wait around to see if any passers by pick it up. and what they do with it once they realise they cant see it as a useable currency
yes, us bitcoiners know what it is and know its value. but if a stranger accepts it and cant even buy a coffee or toilet roll with it.. they will never think about using it again.
remember bitcoins ease of transfer, is not the same as:
ease of use (lack of retailers)
ease of obtaining (registering with exchanges and buying)
ease of understanding (converting 0.00x into common fiat)
so try not to throw $9 of bitcoin at random people without having a bigger plan
think about where people once they become fascinated with your demo can easily and legitimately buy bitcoin.
think about why each person would have a need for it.
think about where people can use bitcoin.
the 'need for it' is more about the demograph of people you are speaking to.
EG.
foreigners - talk about remittance to their home country/family
investors - talk about the asset holding(hoarding) or day trading on legitimate exchanges
consumers - talk about the shops in your area they can use it with
try to think of as many uses/solutions as you can, and then when asking people what they do in their daily lives you can tell them how bitcoin can help them
