Perhaps you could offer up one cash out of up to 10% of CL held by each investor for a limited period. Then again, say three months later (subject to the state of the wallet). And/or up to 100% for investors who hold a small amount eg 10 CL or less. I haven't checked the wallet and the richlist so these are suggestions off the top of my head.
Some people like to play with their tokens and mix and match. I think it is a balance between providing some liquidity for those people, but maintaining the value of the wallet for long-term HODLers.
Would you burn the bought back tokens?
Personally, I'm happy to HODL another 12-18 months and get some bread milk and honey.
