Is there a verifiable record of which real-world entities bought in? It would be nice to have a way to rule out the possibility that they sold it to themselves to create the perception of demand.
In new schemes, you sell 10%, but claim you sold 100% in 4 hours so that you can start a new sale due to the "high demand" and try to really sell with fakely boosted "interested" abusing the greedy human nature.
