Trading can give you a good income if you have a good enough capital but i'm afraid that income wont be steady or stable, i mean sometimes you get profits and sometimes you pick up loses as well so that is how it goes in trading.
not everyone can gain something in trading, there are those who will lose small amount each day, if someone win someone else or many other must lose, depend how much the winner has won
What you are telling is true for trading but earning through signature campaign is good only possible if you are in higher rank as good paying campaigns are only enrolling minimum Sr.Member rank. So you have to also try in service section and see that if any bitcoin job is their according to your skill.
