Both Bakkt and the market got rekkt, and I doubt either party wanted this outcome.
Bakkt didn't flop, the people did who thought it would generate tons of volume right off the bat.
Bakkt is a retail driven platform, launched during a time where the market took a massive dive. Retailers have a tendency to only enter an asset when its price has been trending up for a while, which isn't the case with Bitcoin. I expect Bakkt's volumes to pick up when the retailer's confidence in the price has been restored, so give it some time.
Somewhat of a positive point; Vaneck's trust has seen an inflow of 60BTC a couple of days ago.
