As a newbie what I did is to consult my friends who are into bitcoin and altcoins investing. I also consulted people whom I don't know but have broad understanding and experience when it comes to crypto currency. I also read articles and forums about the digital currencies.
Better to also read in this forum because when I was a newbie, reading here in bct helped a lot in my journey in crypto world. Just read and participate in different topics so you can be informed and updated with what's happening in bitcoin and other coins. If you rank up then you can start earning coins by joining in bounty campaigns. It is really recommendable because for me it is the easiest way to earn.
