Is it necessary for token or coin to pay huge amount of bitcoin or ethuruem for it to be listed on Exchange...
Why exchangers charge millions of dollars to get a token listed on their exchange?
The exchanges are also out there for business. They are aware that you will not create a token and keep it to yourself. You must trade it, and as such you must go to them. Charging for listing is normal for continuous maintenance of the platform for better services.
