In my opinion, bitcoin's price can only be predicted to a certain extent when reading charts. I personally think news like bitcoin legalization and banning, forks, new companies/organizations accepting bitcoin as payment, stuff like that has a lot more effect on bitcoin's price. So yeah. Be updated on the news, keep on reading.
Some good news sites:
thanks for this links, I may have more knowledge to gain by this links you provided, I also want to know when bitcoin going to decrease or increase day by day. so I can predict the price of bitcoin by this, and I want to learn how to read/analyze bitcoin chart/graph to increase my earning every month.
Be careful with that though since by the time you have access to the news someone else will have been trading with insider knowledge for much longer and with much more money.
Technical analyses helps a little but it's not going to give you clear answers about whether the price is going to go up or down. It's about recognizing patterns and knowing when to act on them when you see them forming.
