Shaker costs 4.75SWC per month, and you can earn up to 10 per day or 300 per month. The cost amounts to about 1.5% of the monthly limit.
Quaker costs 20SWC per month, and you can earn up to 15 per day or 450 per month, but the cost shoots up to 4.4% of the monthly limit.
Breaker costs 30SWC per month, and you can earn up to 20 per day or 600 per month, and the cost goes up again to 5% of the monthly limit.
There doesn’t seem to be any rhyme or reason to the cost and daily/monthly limit ratio. It would make more sense to me that the monthly cost of an account relative to the daily/monthly limits should be lower as you go farther up. The biggest discrepancy is the jump from Shaker to Quaker, because your monthly SWC cost goes up by 321%, but the amount you can earn daily/monthly only goes up by 50%.
Is there a reason for this? Sorry if I made any miscalculations, feel free to point them out if anyone spots them. Math is not my forte
