0.253 SBD equals (assumed 0.4 SBD/STEEM) 0.6325 STEEM. So if I understand it right I have to delegate (invest) 1000 STEEM to receive 0.6325 STEEM as a daily return.
That equal a ROI of 0.06325%.
Even if I'd reinvest the daily ROI, the yearly ROI would be less then 26%. Since it's not easy to reinvest the daily ROI probably the yearly ROI will be about 23% 😔
Since I like the idea of @qustodian maybe you can explain how you calculate for a daily ROI of 1% which would be awesome 😊
The total amount of SP delegation is 14K, of which 14K is the bots. 80% of this is given to the delegators. Effectively improving your ROI by 1400 * 0.8 / 12600 = 8.9 % improvement.
The money received today is 0.64 / 14000. The annualised rate is (1 + 0.64 / 14000 * 1.08) ^ 365 = 1.8%, without it, it is 1.6%. Take off the 10% transferred daily, gives 1.44%.
I can check the calculculation for accuracy, but that is the general idea.
Returns are quoted in SBD. Similarly, 9% SBD return converted to STEEM return is 9% * 2.5 roughly or 23.5 %
