The only idea I have around this is to issue a token that will represent a club membership. Like, if the club will go viral, then your membership may be sold at a higher price than you originally bought it.
As an extension, the particular membership may have some additional statuses attached, which gives some privileges in the club, which may also increase the price. If you visited all events of the club the past few years, you may earn an "always there" status, which gives 5 free shots at any event. But, these statuses are not a part of the token and need to be stored in a separate service.
