And since you're a new here, it will be wisely and safe enough to just buy some the major cryptos like Bitcoin, Ethereum, XRP or Litecoin, and stick to friendly and simple crypto exchange. For example, you can start with CEX.IO, its website is easy to navigate and there you can buy cryptos directly by using your card, or try your luck in simple trading or margin trading on its comparatively new platform CEX.Broker, https://cexbro.com/.
