And not in one billion years will Gemini offer anything like that.
You can see where it is traded here - https://www.coingecko.com/en/coins/digibyte/trading_exchanges#panel
The only places I'd consider on that list would be Bittrex, Poloniex and Kucoin. Bittrex and Poloniex are currently changing jurisdictions and ownership and probably won't let you do anything without handing over your ID so there's that to bear in mind if it bothers you.
Kucoin I think let you trade without ID up to a certain limit. People seem to like Kucoin the best but it has lower volumes for that project.
