Daily: Asset 1000u earns 2 points, trading BSC 2,048u * 8 times earns 15 points, so in one day 17 points, 1 round earns 17 points * 15 days = 255 points.
Since the implementation of the deduction system with 15 points per time, the minimum points are 186, so in 1 round of 15 days conservatively estimated to earn (255-186)/15=4 times.
According to this week's record, the worst can earn 70u (RDAC initially earned 30u and later supplemented with 40u), so in 1 round earn 70u * 4 times = 280u.
Each wear and tear counts as 1u (shouldn't be that much), 1 day 8 times equals 8u, 1 round is 8u * 15 days = 120u.
So the cost is 2,048u, profit (280-120)=160u, annualized 160/2048/15*365=190%
If the cost is calculated at 5,000u (because it's impossible to just put exactly 2,048u), but still only earn 120u, annualized is 160/5,000/15*365=78%
If the cost is calculated at 10,000u, can earn 18 points a day, 1 round earns 270 points, can participate 5 times earning 350u, profit is 350-120=230u, annualized is 230/10,000/15*365=56%
