Here is how i started trading ->

1. sign up on Coinbase
2. sign up on Bittrex
3. purchase litcoin on Coinbase and transfer it to Bittrex
4. find a few coins that I like and follow them on all social media outlets
5. find other people that are into the same coin and follow them also for more opinions/data on the coin
6. buy and sell according to news of the coin

This is what I do. It works for me, but doesn't mean it will work for others.
