REQUESTING COMMENTS FROM COMMUNITY
I do not see anywhere that Poloniex and Bittrex has paid listings.
Bittrex has free listings and a required compliance check for coins that have pre-mine or ICO from what I understand. The compliance check involves things like checking company registrations and the persons behind the registered company. BitcoinZ is completely decentralized and no company attached to it. As far as a listing, there is no listing fee.
Poloniex from what I've been able to find, also does not charge for listings, maybe I didn't look hard enough?
If anyone has any authoritative information regarding paid listings on Poloniex / Bittrex please share it.
Just letting the community know as to not mislead the community. Especially seeing the mining reward idea come up for donations, I wouldn't like to see an uprising of miners/community asking "why are we not listed if we donated through mining?"
Of course the donations can be used for such exchanges that do offer paid listings. They will not go to waste and will be invested in to BitcoinZ progression.
