I could say that experience is the best teacher. Trade, mine and observe the charts as prices changes in the market. Read, read and read. There are so many articles not only in this forum but also in news, write ups, mainstream media, join groups in social media, ask questions. Just don't be scared or be overwhelmed by the crypto currency. Everyone started from very limited knowledge. If you want to earn then trade bitcoin and also join a signature campaign. Goodlluck!
