I dont think that any trader can earn each day 5%.

It can be but not for all days. The scenario as below may be more logical,

Day 1 - 5%
Day 2 - -3%
Day 3 - 1%
Day 4- 1,5%
Day 5- 2%
Day 6 - 10%
Day 7- -5%
Day 8 - -3%
Day 9 - -1%
Day 10 - 1%

Total 9-10% but event his scenario is logical but not eash to achieve every time.

for me monthly 2-5% is fine in average

so please dont believe people who says 1% daily interst. It most probably scam!!!

because think that if one can make 1% daily trading gain, why they need your money for investment. 100$ can easily turns 1.000.000$ in a short time!!!

take care on your investments.
