That's correct, they are asking 5M Dot coins or around 24 BTC. You can negotiate though but the asking is now more than $100k in USD equivalent. There is tremendous demand for coins exchanges now that's why these exchanges are making a killing in commissions and listing fees.
Even negotiated down to $100k is ridiculous. No wonder some new coins need such a high premine!

Would be a market for all those dead coins on cryptopia to get purchased by a new high quality team for like 10k, and get forked or completely 'relaunched' with new objectives, whitepaper etc. Would save $90k just like that.
Anyway, lots of new exchanges expected by mid 2018. Trade io and coin lion just to name a couple. I think there will be more competition in the exchange space soon, which should dampen asking prices for listing.
Yeah, a $100k is still a lot of money just for listing. I guess the old supply and demand equation even applies to listing on exchanges. I'm also seeing a lot of exchanges coming soon. That's good news for startup coins that have difficulty listing.
