Just so that we're on the same page, we need money in our coffer so to perform what you've envisioned, thus structuring BountyBa.se (working name) as the proven lending program would guarantee enough funds in the coffer to sustain the venture for many a years.
Yes part of the value of BountyBa.se is that it is funded for the long game. So like any ICO a pie chart would picture how the funds will be used. The more transparent the better, as the perps trade on darkness.
For example, for each case, a single wallet address can be published as the official destination of any funds returned voluntarily as a result of negotiations...and for communicating with the perps. So all coin holders would know when the program is succeeding, and how much will be their next payout.
A potential buyer of the coin could be perps themselves, incentivising them to give up the entire amount in exchange for a non_prosecution agreement from BountyBa.se, and a relative payout, assuming they come in under the radar of any possible KYC requirement for big buyers.
Similarly, there needs to be incentive for perp teams to betray each other, and for fed agents to get involved as moonlighters, if not as an agency.
