You can have a bitcoin even without capital, just join the campaign. You just need to work hard and make constructive post. Dont be in to trading if you dont have idea on it, you might lost your money.
Hmmm. At this time I think it's really hard to earn about 1 BTC from signature campaign only cause they payrate is much lower than before because of Bitcoin price is really high at this time. But at the start joining signature campaign is a good option then you can use the amount of Bitcoin you earned from signature campaign to try trading, it's not easy but it's not too risky just try to learn and explore about it before start then I think you can earn a lot with trading
