The .15 fee is pretty reasonable. I may even consider paying it for a sizable bounty in return.
Here are some of the other exchange fees I'm aware of from prior coin campaigns I've helped with:
Cryptopia.co.nz: Cost is 5,000,000 of their DOT coins to get listed, or about $200,000 USD
Coinexchange.io: Last quoted price from them was 4 BTC for a listing
CoinsMarkets: Only .5 BTC to be listed... but I'd be wary for now with all of their technical issues
Bittrex.com: They don't charge a fee exactly, but the process is long and you'll want to wait until you have a solid, established coin. They're very picky. There are co-marketing opportunities (if you're incredibly lucky to be chosen) in which you contribute some funds for your launch.
Binance.com: After the coin takes off, enter their monthly contest. CryptoRand recently tweeted that the winner has to kick in up to $1mil USD to be listed.
Keep an eye on Nova Exchange. They are supposed to be opening up their doors again in the next month or two, under new management.
Hi!
If you can afford to help out with listing, or actually get us listed somewhere, I'd have no problem getting you a larger bounty. What amount would you consider to be reasonable?
I tried sending you a PM but wasn't able to due to your message settings.
Let me know, and thanks in advance!
I like this project, got you some promotion on Twitter, see PM
PM received, will reply back shortly!
Nice node growth by the way
