Can you not just merge the market caps and get it done?
To me the proposal looks to be a simple change from new DACs honoring PTS/AGS to also now honoring BTSX; coupled with drawing together the devs and value from certain DACs and maximising their contributions, all then becomes within a new BTS. The benefits far out way the losses.
Keep it simple, get it done!
Market caps are massively volatile though, if the exchanges don't have a lot of volume, then someone could pump the hell out of the small DACs before the merger happens.
I don't think vote/dns should get as large a slice of the pie as people have been suggesting, purely because they weren't functioning DACs in the first place - it's just double paying AGS/PTS holders if we merge.
I think PTS should get a larger share than AGS, like 75% vs 25%, infact.. i don't think AGS should get anything since they were already snapshotted for BTSX/VOTE/DNS/ - why pay them again? It was a donation to developer funds, so this is like a refund to them.. creating funds out of thin air, not cool.
