now BTA have interest supply by who short BTA. but it is too small. and float. I don`t calculate how much it is . but I estimate it less than 4%. it is less than YUEBAO,

how about set a Min interest of BTA. it mean if someone short BTA, he must supply a MIn interest . of course he also can supply a extra interest like current. and the min interest is set by delegate like feed price. call it feed interest. but interest only change one time by a long period like 3 months .

on early stage of BTA developing ,there have little exchange in BTS client ,so less fee increase interest of BTA, but can set high MIN interest to attract people reserve they wealth to BTA. after BTA is popular. we can decrease the interest of BTA .

...consider this idea also:

what about we add as interest the difference of total dilution 50 BTS/block minus current dilution (now for example 7.78 BTS/block)

that means 50-7.78 = 42.22 BTS/block given as interest to BTA

?? (That will of course reduced when more delegates pop up with increased payrates)

That means only when ALL 101 active delegates manage to take ALL 100% payrate then the added interest from dilution will go to 0, (that will likely never happen since we will have delegates with lower payrates at any moment in time plus when the market cap increase to much some of them will be forced to decrease payrates)

after all untill then, the transactions should be so much that the interest from the shorts alone etc. should be high enough..... please imagine the positive impact of that !!!
