I was thinking about writing up a large paper on this idea, but I think I'll sumarize the thoughts I've had.
If I was master of bitshares, I'd consider a new sharechain that consists of something like 50% airdrop, 50% bitshares family.
The shares do not need to come into existance all at once.
For example, I decide to distribute as follows.
1/2 goes to bitshares family, of which (PTS?)
1/4 goes to BTS
1/4 goes to AGS
The other 1/2 goes to
1/4 BTC
1/8 LTC
1/8 DOGE
The first rollout would only create the BTC shares and BTS. So 1/2 of the shares are in existence at rollout. Then when AGS is available it would be added as would LTC and Doge.
Perhaps there are problems with secondary genesis blocks, but it seems doing the airdrop in stages might be feasible. If not, then I'm not sure how to include AGS if you want first mover advantage.
Make a logarithmic multiplier so that the largest accounts are normalized. Someone who understand logs better would have better ideas. Cut off accounts that are dust transactions on the bottom end. You could even out every account, but that is too easily abused and will alienate people with large amounts of capital. The multiplier needs to be thought over, but should help decentralize ownership while not alienating those with large BTC holdings.
I would name the new branch
BitChairs. BTC3 for short.
Think about it guys. What you gain in 50% dilution will be made up with increased market penetration and interest. I'd guess it would also increase odds of success immeasurably.
