Hey bro ! In simple words 101 is a non chip card and 201 is a chip card. Well the idea of dumps is to swipe for what ever you can sell, doesnt matter what it is, its completely up to youre imagination, you can buy electronics. condoms, cigaretes or jeans, gift cards where ever youre imagination and abillities take you. The idea is to buy something you can sell. Cant help you much with the bin selection because i dont work in that region, but usually ver rearly someone will share that info(so that ppl dont over kills personal/privat bins), most likely youre gona have to experiment youre self and figure that out.
P.S this is a very general answer so dont get me wrong
