If you are a total beginner, you probably should go to an exchange that has LTC or even Doge market, allowing you to practice and get the hang of it with very small amounts.
Trading without losing money means skills and before you master them you are going to make a lot of stupid mistakes, whatever the exchange, specially in crypto where weird things can happen. It's better to lose five cents while learning the hard way than 1000 bucks on your first day because you stuffed the order.
