There is no minimum start to trade
but this is related to a person's financial ability
And whether he wants trade to be a basic or subsidiary profession in his life
And ........etc
in short, no one can answer your question
Note: of course, the amount must be more than $10 in order not to have problems placing trading orders
I agree with you that we need minimum capital to do business No matter how big you are you can never start a business if you do not have enough capital. But I think if you start a business with $ 10 to $ 50 the better it is the greater the amount of profit.
