I'd say a low cap, but a long staking period. Long time commitment seems much more valuable than money invested.
The 'skin in the game' argument doesn't seem to work all that great here on Steem. Maybe we should recognize that both time and money are investments. I would value a time investment over a money investment for a custodian, but only when the commitment is long-term.
6 months is short imo. Yes, things can change rapidly in crypto-land, but we don't want custodians chasing hypes. We want structural progress towards DACs that someday will be massively adopted.
Ah, interesting. Some think 3 months is too long. Finding consensus is fun. :)
Right now, we have it set to 3 months as we're discussing it. Some think it should only be 1 month. Maybe something like 4.5 months would be a good compromise?
