Most institutions like banks set fees like this purposely because they really don't want to waste time unless you are investing millions.
It's just not worth it for them to handle the account unless the fees they make are worth their while
It is not about fees actually, it is about leverage, i.e. the amount of money you should borrow from the broker to open a position. For example, a broker says that you can start trading with just 100 dollars while in reality the minimum lot with which you can trade is 10,000 dollars, otherwise known as mini-lot (full, or standard lot is about 100,000 dollars). In this way, to be able to trade through such a broker, you would have to use a leverage of 100:1. That basically means that if the price changes more than 1% against your position, you will get a margin call...
And your account gets wiped away unless you add more funds to it
and the fees that you are paying for this type of service.
You can rest assured that the leverage will be particularly insane
