As a newbie, my advice to you to "observe" the market. Not only bitcoin but also other altcoins too. There are good projects which will bring good profit on the long term.
Before investing on any altcoin I would recommend to read whitepapers of the altcoins. (Teams, Roadmap etc.. all must be considered before trading)
I will recommend below blog to follow for Technical Analysis which is very useful for trading.
