Trading margin can make you alot but you can lose alot too, and faster than you think. I'd say its important to get practice with low stakes so that you're not bricking it when things don't go your way, and believe me that will happen at some point.
Not trying to put you off or saying dont do it, but be real careful and keep stops tight. 3K might be profit bt its still 3k right? Wait till the trend is your friend too. As said before if you're buying ONLY buy the dips or you'll be upside down before you start.
All the best .
