I must really commends you on your efforts to bring down the bitcoin language to everyone, not just to anyone but making sure to print out a handbill bt I can call it sticker to people around to be able to learn and know about bitcoin which I think is very helpful to people around and I know stickers travels very far away whereby people must see it.
OP's action is highly commendable. Investing money and time to come up with selfless service is an act to emulate. This action might look insignificant but one or more people might have become interested in bitcoin through the information. Bitcoin awareness is what will lead to increased adoption, therefore we need to appreciate anyone that is spreading the news about Bitcoin.
While paper-based advertising may not be taken seriously, there are alternative approaches to promoting Bitcoins. yes, we are all here expected to be adaptable and open to new methods that align with the preferences of your target audience. But, at least consider using digital platforms and social media to reach a wider audience. Creating awareness is a good thing.
Advertisement strategies depend on the location and the level of enlightenment of the target population. In advanced countries where the level of education is high, online or digital advert will be the best option. But the paper advert is still very potent in some countries like mine. Most businesses in my country use handbills and billboards to attract customers. But to get wider coverage most organization combines both online and offline advertisement strategy.
