The development of Bitcoin is still in its infancy, and too many people do not understand it, and are even afraid of embracing it in the encrypted world. On the one hand, I agree with your methods and efforts to allow more people to accept and participate in the encrypted world. On the other hand, I also admire the early participants. Their courage and cognition are worth learning from. Too many people will all participate in the middle of Bitcoin's development, that's for sure. So I hope you stick to this meaningful thing.

Bitcoin knowledge is vast and you cannot learn it all in a few days or invest in it in a hurry. He gave everyone a chance and it was up to them to take it or not. Like me, I know about bitcoin through a friend of mine, but my knowledge is not taught by him, but I learn everything by myself through forums, youtube...It can be said that knowledge about bitcoin is everywhere on the internet, as long as you really want to learn, nothing can make it difficult for you.

the stickers are very nice,
but I would suggest, it would be even more appropriate if the sticker was posted, web or link, to learn about bitcoin, so that people understand what bitcoin is and what are the benefits of investing in bitcoin, and what are the risks of investing in bitcoin.

what you do is a unique and interesting activity.

Good initiative with you OP and those continuously learning make you more knowledge that could be used to share with other people and of course, getting curious of it they make probably change your life in an instant, this could bring a possible life changer with you or to that particular person saw the stickers, it's good too if you might add some information with it so you can guide them whenever you leave that sticker.

Have to say the only stickers I've ever come across in my wanderings (apart from on shops to signal an accepting merchant) have always been neutral (no message), or even funny/non-serious (I distinctly recall the rollercaster Bitcoin person thing). Hard to spread a message without providing some kind of evidence, but I do always wonder what a person sees first when Googling. Definitely need to think about adding this forum link

I think in the Philippines that will work best. A lot of their public vehicles can be commissioned to place stickers or banner ads in exchange for cash, and about 10-20 bucks usually do the trick. Aside from that you can also increase people's interest in bitcoin through word of mouth. I've heard there's a lot of tattle-tales in that country so we may as well use them to  increase bitcoin's reach to the masses by informing them foremost of success stories that came about from investing and working on bitcoin. All in all, no effort is small when it comes to letting people know that bitcoin is a thing.

Stickers are basically gorilla marketing, and its not bad at all and every bit helps. If we had 1000 people all around the world doing the exact same thing, it would become a huge wide spread mainstream media news, but one person is not that much news, yet its as best as you can do.

On the other hand, if we could do more online, because crypto is an online thing, and I believe that we are going to end up with something much better when the time comes and with those online spreading of awareness we are all doing, its going to keep on growing. It's not just about price, its about how many people are involved, because the more people equals the better adoption for it and a better future.

Another effective method for educating the public about bitcoin can be stickers. But since the majority of people don't know anything about bitcoin, your decision to distribute stickers in that manner without first briefing them about bitcoin makes not much sense to the general public.

Despite your shyness, you should have at least hinted at what they should know about bitcoin or, better still, directed them to register on this forum to learn more.

As others have said, you have to show a QR code that leads to the official website about what bitcoin is or other articles that are learning for the general public, but I don't know how the OP's steps have been, has he updated a new striker or implemented other methods but with make it easier for the general public then it will be a useful thing for those who are certainly interested in bitcoin.

That's a great step to signal them to go to this forum to find out more but if they are still nervous then there are still some outside platforms who still teach bitcoin easily in a way to understand it, here only to discuss and learn even in doing it when they already know the basics.

Promoting Bitcoin is a good thing, but is not in hurry ways,  we know very well that some countries banned Bitcoin but their are ways, two of my friends are now in Bitcoin investments because of me, they don't see me going to work or searching for work and my parents too are not rich to send me money like that but I'm still  buying what I like to buy, so one of them ask me hey, which work are doing,? after he asked me that question, he pleaded back,  and  said we know you are not working even your parents too, don't have enough money send for you, but have money to spend for whatever thing you like, are going to work for night? and  I answered him, I'm in crypto investment, Bitcoin investments, and he ask me what is Bitcoin? And I told that Bitcoin is made to transfer in the internet. And digital currency was intended to provide an alternative payment system. and show him how invest, impact some knowledge for I told him how to invest I explain many things for him even the risk involved how to understand the market. The next day, him and the other friend came to me again I tried my best for them and I ask them to join the forum, and a website to learn more.
