Where do you think I should start?
many say Binance is safe and highly recommended.
What about the exchange of your choice?
Many large exchangers trade tokens that are in the wallet. If for ethereum, I think holding it for the long term is a good choice but if you want to sell it, you should choose an exchanger that has a large liquidity such as Binance, Huobi or Okex
