First listing will be on 20th December. There are still some negotiations but we should get an update about which exchange it will be very soon.
It's not officially listed on ED and the volume is pretty low there so I personally do not think that the price is representative. Some people sell their bounties at the moment to get quick bucks, don't expect such a low price on official exchanges but we will see.
The first "use case" of HERO will be on HERO's own platform (herosphere.gg.) and fully integrations happen until Q2 2018. Around the same time, there should be the API for 3rd parties available. Demand should rise at this point latest.
There are several marketing campaigns planned to make the platform more popular, also there is already a strong userbase (250k users) on herosphere.gg
Hope this answers your questions properly. If there is anything more don't hesitate to ask
250k registered users or?
how much are from them active?
I see trades in etherdelta but observe The price is in dump since listing in it with a considerable volume per 24 hours. Simple factors causing the dump as bonuses of invetsors and bounty payments and nobody waiting for the 20 December that still no exchanges are mentioned to be listed on. Am not saying that this is a shit coin but can't be convainced about the success of the Hero platform. Q2 of 2018 is a long period to wait when no available prototype or product. The team is adding not much value to the token.
