The OP isn't new to bitcoin. He's asking question pretending he's new to Bitcoin. He isn't a new user in the forum. He didn't reply to any help he's received in the 3 threads he's opened.
I may not like to divert on his other threads he created which he also didn't make a follow-up on the from people's reply but that isn't a justification not to reply his request on what he asked, someone might have been on this forum for years without having experience i trading.
OP i will like to say make my contribution that you always read about exchange ToS abd understand them, am familiar with the limit on the minimum withdrawal of $10 by most exchanges, but in numbers of their buying and selling attempts has to be what you will discover by yourself from the particular exchange you use.
