I have been using IDEX recently to grab erc20 tokens.  It is a decentralized exchange like EtherDelta, but the UI is much easier to navigate.

I am trying to get $DGPT listed the exchange.  I have submitted a request for them to list it.  I think if additional requests come in, the more likely it will happen! More volume and liquidity is only a good thing for $DGPT!

Fill out the form from IDEX here:

$DGPT Contract Address: 0xf6cfe53d6febaeea051f400ff5fc14f0cbbdaca1
Decimals: 18

Thanks!
