bispex token BPX itself is built under the ethereum smart contract network ,various smart contract blockchain platforms like ethereum there are many mate you can explore including eos neo waves and others ,the difference between tokens and coin is quite clearly explained by friends community above
That's why the developer if the bispex called it as a token caused by bitspex is building on under ethereum platform as the main blockchain.
I think it's very easy to understand and some people above me have already provided the meaning of the coin and what's the differences of coin with token.
Token is an asset which can be considered as security at the same time as it doesn't have utility. It's really simple how to understand the definition of the token or asset.
coin is far better than asset but it backs again on the usability.
