investors are invading some exchanges why not developers? i know listing fee can be huge but few exchanges are just scam practitioners, developers should take their time to check out scam accusation thread on this forum and see how many people are been ripped off by these so called exchanges e.g idax p2pb2b among others
If you notice, only scam coins are getting listed into scam exchanges. There can be some exceptions like MTC was listed on hitbtc but as of now it had been delisted. Some times developers choose whatever offers they come cross with the intention of reducing the listing costs. This might be ending up listing scam exchanges. But, a dev team that is caring about their investors will never go on listing with an exchange which had failed to keep their reputation high.
Doesn't make a ton of sense to me because the cost for listing a coin on an exchange should not be a significant cost compared to how much money many of these projects are still raising
No, not all the projects are good in attracting investors even they are backed with wonderful concepts and showing good progress in developments. As far as I have heard, listing in big exchanges is more than an average project is able to rise through various crowd funding.
