Yes, from home you can do it only with social media services. Twitter, facebook, vk, pinterest, instagram, youtube and others!
Anyway, soon bitcoin will kick out fiat currency, and will in every shop, in 10-15 years i think.
Spreading the news regarding bitcoin through social medias for sure will help to make bitcoin more popular. But to kick fiat, I doubt it will happen in the near future. There are only few countries already legalized bitcoin which means bitcoin still remain as an asset on most of other countries.
