Bittrex is a U.S.-based option to trade altcoins. Many users trade on foreign exchanges for altcoins because America doesn't have many platforms with a wide range of cryptocurrencies. If range is what you're looking for in the U.S., then Bittrex is a solid choice.

I like that it's a small minimum fee. This allows for smaller traders like myself to trade more frequently than exchanges such as Binance.

What I like best about Bittrex is the amount of coins that it provides that customers can buy. The recent USD markets that was added this summer of 2018 that allows cash instead of having to add different Cryptocurrency to exchange for another Cryptocurrency.
