I have funded my first witness account, if this goes well I will create 10.
If you have fund today the 6 account with 50.000 Gulden for 9 month and 4 accounts with 50.000 for 3 years then you have made a mistake. Better was 1 account 300k for 9 month and 1 account of 200k for 3 year.
6 times 50000 9 month gives an interest rate of 2,13% versus 1 account 300k for 9 month gives 4,12%
4 times 50k 3 year gives 4,6%, while 1 account of 200k for 3 year gives an interest rate of 6,68%
All mentioned interest rates are on annual base
Sorry
You can calculate this with the calculator
https://www.dactual.com/witnesscalculator.phpI only created 1 account for 175 000 but no rewards after 677 blocks, if I start getting rewards 1 per day the next account I will create is 250 000 because estimated reward frequency is 0.99 on this account and I want to make sure I get 1 reward a day for all witness accounts I create.
