All coins which are getting de listed from novexchange can get listed in coinscontrol.com exchange by just paying listing fee of 0.10 BTC ). Coin will be listed to exchange with in 5 working days. For more info Dev's can contact
support@coinscontrol.comexchanges that require "listing fees" almost always turn out to be scam in the long time...
I think asking for a fee is legitimate since they have to dedicate some computer resources and take the time to update and resolve any unforseen issues / absorb potential double spends etc.
Yeah, it's ripe for abuse though and undoubtedly it has been.
If the player more exchanges, the cost is reasonable, although more expensive, but it makes sense, your project will be on the line there will be a lot of people involved
