The thing with Bakkt's Bitcoin backed futures is that you don't have to accept delivery of the coin(s). In that sense the futures are cash settled until traders choose to actually get them delivered. Futures traders aren't your average hodler type of people, they just want to speculate on the price.
It's kinda confusing the way they marketed themselves, so I can understand why people are disappointed. The thing people do have to blame themselves for is that they expected Bakkt to sky rocket the price right off the bat. It takes time to build up volume and a large clientele. If that clientele on top of that isn't interested in claiming any coins, it's safe to say that there won't be much of a positive impact ever.
I would have preferred to see Bakkt empty the OTC market to fill its reserves, but it doesn't seem like they will ever run out of what they thus far accumulated.
