What's your opinion in educating these petty traders and letting them know more about Bitcoin because I believe this is amongst the grassroot adoption which starts from the base as they do transact more often than some of the big companies we hear of. Although the petty traders do little amount but it is most often on daily basis.
What steps would you take in drawing the attention of the traders to Bitcoin?
Bitcoin is not for everyone. You can try to educate them by several means such as conducting some sort of bitcoin awareness program in areas where you see most people are uneducated in bitcoin or you can try to make infographics if you don't have much time to discuss it. Then just give away the infographics on the streets for them to read it on their own pacing. These are just a few examples of what you can actually do in educating these so-called petty traders.
However, it will be all up to them if they will give bitcoin a shot or not. It's still a personal preference after all. We can't force everyone to like and do bitcoin because we have our own preferences on how we want to do things. And just because it worked for us, it doesn't necessarily mean it would work for them too. To each his own. We can educate, but we cannot impose.
