Trading with leverage isn’t bad, the good thing about it is that it magnifies your profit. But then it also has its bad side which is magnifying your losses as well. I wouldn’t really say that it is that bad, as long as you know what you are doing and you are very sure that the decision you are about to make is going to work out and you make profit from it, if not then you are going to end up with a huge loss.
Anyone who is trading with leverage can use a little amount of money to make about 100% of what they’re trading with, but without leverage you’re making less, so This is why a lot of people like to trade with leverage. But at the same time they are taking a huge risk.
I have to say that good side doesn't worth the bad side for me. If you are a veteran of it and can make a lot of money with it then by all means go ahead and do it, however that doesn't mean that you should do it, if you are good at leverage then you will most likely be good at spot trading as well. Knowing the direction is the most important part isn't it? If you know the direction then you could do spot trading and yes you will earn a lot less that way but you will lose a lot less as well and would guarantee that you would be holding at least some money.
I tested it before and I dislike it, losing all of your money if it goes on certain direction never really work well with me. I like to lose a bit if I am wrong and earn a bit if I am right, that way I would be doing a lot better. In the end it really works as perfectly as people hope it would be whereas leverage just takes all of your money away if you are wrong.
