We do need much higher trade volume to get listed on poloniex. Give DIME some time.  Within the next weeks/months we will have a mac wallet, bootstrap installer, new compiled downloadable wallets with upgraded libraries like ssh, ....perhaps an android app soon (depends on coinomi.com decision), .... 

Trading DIME on cryptopia: https://www.cryptopia.co.nz/Exchange?market=DIME_LTC and novaexchange: https://novaexchange.com/market/LTC_DIME/ is working very well.  I did not test the other exchanges.
