I personally prefer to keep myself OPEN to everything, as per the situation demand. And I doubt if I require to explain the logic because its so obvious. When you are open to any style/way, then you increases the chance of making profits, and thats really what we are required to do in order to be successful.
Right now, I trade with
FXLinked, which is licensed by FSA, and holds great value with lovely features and facilities. They have over 200 instruments which includes Cryptocurrencies too, so I like trading through this.
