stop wasting your time and buy $20 worth of bitcoin already! that is a much faster way of reaching your goal to "start trading" as you put it.
if you don't want to buy then sell something that you have for bitcoin. go to goods board of bitcointalk and start a topic selling something you have for bitcoin and use that to start your trading.
if you don't want to do that either, then start doing some job or offer some service to get paid in bitcoin. for example you can do translating jobs, coding if you know how, designing, photo editing, and lots more depending on your skills.
