If we are going to be approaching exchanges, I think the best bet would be to start only with Poloniex and then move on to voting on Mintpal.
Those two are all you need - even Crapsy is no longer nearly as important as it used to be. Polo to start, then Minty when things get rolling....
yes, poloniex and mintpal are better than dgex. dgex charges exorbitantly high rate for btc withdrawals and you never know when btc arrive at your address
we can approach bter too
