Definitely. To be on the safer side, I suggest using legitimate dealers, companies or use an escrow to make the trade safe. There are vast majority of ways to cashout. From local bitcoins to selling on escrow powered platforms like local bitcoin or selling directly but only with a trusted third party.You can cash out your crypto if you want to by requesting a withdrawal on the exchange where your coins/tokens are.
Before the withdrawal process, its your choice to sell/trade first to other coins or directly to fiat currency. If you are transferring it to a third party app/service, make sure you are using the official and legitimate one to avoid loss of your money.
