Well, there is no "the way". Trading is experience in my opinion. And you seem to be pretty new.
Gather experience about crypto coins and think about which coins has a good future and then invest into them.
Check with online trading sites like localbitcoins.com or kraken for good experience in trade, else Selling bitcoin in person can, in many ways, be the easiest way to pass on your digital currency. Simply scanning a QR code on another person's phone and accepting cash in hand is about as easy as a bitcoin transaction can get.
