I am still fuzzy on how DACs worth within the overall Bitshares blockchain system.
It seems to me though after reading more about this that there are a few good ideas.
Airdrops can not be sold/traded immediately. I believe Freetrade (the mmc guy) suggested we randomly add a delay for how long until shares can be transferred. Thats the best as there is no unified time where people will sell their shares.
It seems to me that a % of any new DAC could be airdropped and it would be useful if Inviciticus led an effort to mature this technology.
This allows the individual DAC implementer to decide what % to airdrop and to whom. It doesn't need to be done at a higher level.
I like the claim system, however I am afraid it leaves out people who do not hear about it in time. I would also suggest that people look at targeting addresses that have had activity in the past 3 months or possibly shorter. This gives you people who are actively buying and spending cryptocurrency. It doesn't help with the wasted/unclaimed coin issue, which I now realize drains value of the DAC. (Dividends are still sent forever to the unclaimed shares.. )
One thing you should look out for is creating to much opportunity where people will be offering to buy emptied wallets.
Although in a way even that is useful, as it will spread the Bitshares concept.
