1. no, i never buy an illegal things with or without bitcoin

i think we're no need bitcoin to buy illegal things, we can buy with cash thoo

there're to many "good things" that i want to buy with bitcoin. there is no illegal object that I think
2. with normal bank system, since not many people are familiar with bitcoin. for safe and confortable. and i think never can be replace.. i guess for this time.
