Taking out the 12 trust nodes (why do two have transactions?) only the top 21 accounts (1.4m of 2.8m) will be making money off of this system. LUKS GUD
Not to be a "hater" bro, your math is terrible.
You only need ~50 MicroCash to get interest (that is you're paid back more than your fee) given the number of accounts (about 100K). I'll show you the math.
100000 * 0.005 microcash (daily half cent fee) = 500 microcash total in fees
50 MicroCash as a percentage of the total MicroCash in existence is 50/2800000 as there are 2.8 million dollars in existence. This number is %0.0017 of all the MicroCash
We times the percentage of MicroCash an account has (0.000017) by the fees (500) and we end up with 0.0085 being paid back. Now if you can remember, the fee is 0.005. Now let me show you one final thing.
If you have 50 MicroCash. 0.0085 daily interest - 0.005 daily fee = extra 0.0035 MicroCash per daySo if you have 50 MicroCash, and not even counting transaction fees which are also given fairly to each account, you would get an extra 0.0035 MicroCash per day. No fee, extra money, for a relatively small amount of MicroCash. Now I hope when you design encoin you do a better job with the math. Make sure you carry the decimal.
