it can be any amount. although u tend to benefit if the amount is bigger.

actually RM93 oso can. but its not wise to make investment every month or everyday, cos the comission and whatever fee u will be paying to the broker bank will be quite high. so better to save up say, RM5000, then one shot go into 1 counter. in that way, u will save the commision fee instead of paying if every month/day.

The Dividend you receive do not need to pay further taxes on it... cos it's already taxed at 10%
