Where do you think I should start?
many say Binance is safe and highly recommended.
What about the exchange of your choice?
You mentioned exchanging 2.3M$ worth tokens but the total token worth of that wallet from etherscan is 22.5M$+ and ETH worth is 1.6M$+. If at all the wallet belongs to you (obviously looks like an exchange wallet), of course you might not be able to exchange all those tokens on a single exchange since some won't be listed, Binance, OKEX, HUOBI, KUCOIN should be your best choice to convert the tokens to BTC or ETH before gradually selling to FIAT. Exchange for selling to FIAT will depend on your location.
