OP, Your daily interest value is wrong for couple of users.
Condoras charges 9%weekly so it come as 9/7 =1.28 % daily.
Tracaspacy OP specify the interest as in week basis, so daily interest is not valid.
Parodium is charging max of 5% monthly or 50 dollars, so daily interest does not make sense.
LimLims charges .5% daily and Chrispops charges 7.5 % for 1-7 days.
I guess the interest varies and there are factors that lenders consider before they approve the loan. Example is a non-collateral loan from a Legendary member that is very active in this forum versus a non-collateral loan from a Legendary member that is not active (in replying and in discussions) but known in this forum. Maybe both loans will be approved but interest will be different because of the risk involve.
