Upper comment may be one way. But after selecting a broker you should ask him about his earnings. Bcoz some brokers are not having much benefits.
Lets say about real estate agent or brokers. From morning to evening they try to sell pieces of land and they tell you good things about that particular land. But most of them don't even have a single piece of land of their own.
It's pure gamble if you don't understand technical analysis. even if you trade for long term, it may happen that you stuck in same coin for two or three years.
So I'm not saying you to be specialist in technical analysis. But you should choose your broker wisely.
