If you are in the US i would start with Coinbase and their trading platform GDAX. With regards to trading strategy it is dependent on your personal preference and the time/resources you have to devote. I am using the buy and hold method which has worked out well due to the steady price increase and minimal volatility the coin has had over the past two years.
