Well , I agree with you, I like DEX , and I use it very often
But , even people who have been mining since early btc times and have a reasonable knowledge of the blockchains , find hard sometimes to make a AltCoin /AltCoin conversion
An I find shapeshift the simpliest way
Anyway,this tool was an experiment , I wanted to learn how to link stuff
I will work next on linking steemjs with bitsharesjs to exchange Steem for other coins using DEX ,or any other idea I find , hopefully at the end I will get something useful :)
