This has been discussed at length over the past 2+ years by original Parity and W3F folks, a lot of interesting ideas. My preference is something like a 50% discount to proven tastemakers and investors with a 5-year lockup and requirement for active public support for Polkadot. We had a lot of good names in previous private investment rounds for DOT who have never spoken a word publicly about the protocol, which is problematic.
