Why not kill several birds with one stone?
1.First do not wait for 2 Bil, start now when we are at 3.7Bill.
2.Every new block has 50 additional BTS found on the blockchain. Some of them will be destroyed if less than 101 delegates with 100% pay. I do not know if all of those should be used for dividend or just say 50% (the one that are burned are effectively (and can be thought as) a stock buy back, which is also beneficial for the DAC), so lets go with 50% for now.
3.So up to 25 BTS + plus some transaction fees are available for dividends. Use those to buy bitUSD (the exact formula when and how to buy those can have a lot of variables) but for simplicity lets say general buy at the peg (or below it if some bitUSD are available below it), and not more than 15% of all available for sell.
4.Each dividend day (monthly or quarterly) send those bitUSD to all BTS accounts proportional to the amount held.
Should be mentioned that those dividends seem to not to bee to excessive - about 3.24% at 2.5Bill supply (2.20% on 3.7 Bill).
So we have achieved:
- deflationary system ( to the likings of a lot of people)/ company that is buying back its shares contently; and we have got rid of the inflation complains/concerns;
-That pays actual dividends (and not achieving dividend like returns);
-In the process we have added (arguably) additional demand for bitAssets.
