I would suggest starting to invest with a small % of what you plan to invest in. It is a great way to get into the market and learn before you dump all your money in. As for what coin to start off in, I would look into a coin that is safe, something already in the top 20 market cap and is already established. Try to stay away from coins that recently surged and pick something that is undervalued. I would suggest looking into DASH, XRP, IOTA, XRB, ADA.
