Have you ever converted USDT -or any other coin- to cash?

Because someday, after making all those trades on crypto exchanges, you will eventually want to cash out some money for living.What's the best and easiest way to do so, and with the minimum fee applied to it or no fees at all?What I'm asking for is an instant converter or something like that, not like Localbitcoins where you have to wait for a buyer to get cash.PS: Don't know about this onehttps://www.cryptonator.com/converter, but it shows me a specific amount for converting USDT to USD. Based on what, I don't know. via /r/CryptoCurrency http://bit.ly/1R8MczW
