Litecoin because Blocktrades.us does not have EOS yet :) if Blocktrades.us has EOS or if poloniex or bittrex had EOS you could just use those! since exodus wallet needs a coin and bitcoin can have $1 or more sometimes as transaction fees, i thoight id side step it completely and just use litecoin to garuntee a cheap and fast method of sending money to your Exodus Wallet WHICh has litecoin built in so like i said in the beginning u need exodus wallet to do this method as its all about hwo exodus wallet has EOS built in which makes this all possibkle! shapeshift,io is also the built in exchange and so it makes it SO easy!
