In many cases the new token isn't necessary to the model beyond the initial fundraise. So what I'm wondering is whether there is an ICO model that preserves that speculation value for backers without requiring the long term success of a completely new ecosystem?
Hope this makes sense and isn't too rambly,
It is clear, yet a token (or mosaic) does not need any ecosystem of its own. It relays on the processing, community and team of the supporting cryptocurrency, such as Ethereum or NEM, etc...
Alll the token needs to have is a place to be traded, which is not much of a problem as nowdays there are even peer to peer systems for that and it is easy to incorporate a token into a marketplace.
Does this make sense?
