Just because the OP was already listed on exchange site doesn't make better than most bounties we have in the altcoin session for the coin utility, trade volume and concept will determine it was indeed better. However, I will advice the OP to use two payment option i.e their coin and BTC.
How can a coin not even listed in exchanges have a trade volume? It may never been listed in an exchange, ever.
Coin utility isn't a warranty also, because a project may be amazing but never accomplished.
If the coin is already listed, you can analyze the project more clearly.
You also know how much it is worth.
However I agree with you, 0.02 BTC volume is ridiculous.
