Yes, please let exchanges know you want RaiBlocks listed.
I've talked with Bittrex, Poloniex, C-Cex, many, many others over a period of almost 9 months trying to get accepted.
I doubt many are more irritated at the situation than I am, if *any* of them would contact me back I'd be helping them get it listed.
Exchanges are prefering cloned shitcoins over new tech coins; i guess their main interest is gain/effort.
In any case RaiBlocks are really promising and i belive they will be valued rightly sooner or later, maybe trying some new-notsoestablished exchanges is the way to go, since they could attract a lot of users (look at how many pages the trade thread has).
Bloombit i.e. could be a good bet.
