If by petty trader you mean the average low income earners that arent probably not used to technology or digital asset, well first you start your education by telling them about digital technology, if they dont have functional devices you can advice them to get one, I also recommend a great deal of patience with them, its really hard for those type of people to believe in digital asset, you show them with examples how its better than the means they are already used to, and again you give them the opportunity to grow on the foundation you have already laid for them
This one really need some long patience and its true that handling out someone who do have zero knowledge about tech or on how it do works would be the toughest challenge of all.
Educating someone specially on trading wont really be something simple yet you would really be keen even on the slightest detail so that they would able to follow you on.
We know that not all does have that kind of long patience on teaching someone.You could really actually give out some key points which they could easily deal and
understand it but always anticipate that things wont really be fine along the way.
