I Would like to ask about some Exchange where some project's IEO are running, How Much worth of those Project that are Listed for IEO in these Exchange.(Latokens,Exmarkets,P2P2B2B,Sistemkoin,ProBit)
I think its better to contact them direclty and ask how much is it. As i understand the listing fee is different for every exchange its depend how popular the exchange is you want to list your coins, much popular the higher the cost for listing.
