base on your experience OP, I think you have found trading the best place to stay. Many had found it difficult but haven't you said it, this means that you are doing this comfortably which is the best thing to happen.
In regards to future trading, never mind it, and don't bother yourself about that. Many have tried and later on, they still get back to spot trading and that simply it means it was not good to use that strategy.
I just started trading not that long now and I don't know why people doesn't always talk about Spot trading and how less risky it can be when compared to Future trading. ...
If you carefully read the topics that are posted on the forum, you will notice that spot trading is the safest not only for beginners, but also for experienced traders. As for margin trading, beginners need to stay away from it, because otherwise you may lose your deposit.
In fact, spot trading has been talked about a lot than those future trading which it believes was riskier of all types of trading.
