I'm Mary the ED of Holochain and we don't have a native token on Holochain. Holo (which is a separate entity from Holochain) is a distributed hosting company and Holo token is our ERC-20 token that is a placeholder for the network microcurrency called HoloFuel. 

We don't spend much time trying to compare HoloFuel to BTC as we are not attempting to be a 'store of value' per se. HoloFuel is a mutual credit currency that is purpose-fit for backing the asset of Hosting power and capacity on a network and its primary utility is for app mangers to pay hosts for app hosting services on the network. HoloFuel is a currency app built on Holochain which is a peer-to-peer data integrity framework. 

We don't ever refer to anything as Holo coin so if that is the starting point of a conversation it's probably not all accurate. The part that was accurate is that we are not PoW or PoS and there are other ways to ensure network security when the design is to match a different purpose.   

Feel free to find me in other spaces. I chanced upon this chat because a friend attending the conference in Japan. If you are there I hope you have a great time!
