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. I found more pleasure in spot trading that had given me peace of mind without bothering myself of the fear of losing trades. Although spot trading is not a get rich quick type of trading because I don't have to leverage, making it very slow to make good profits but best for me.
Spot trading and Future or you called it Leverage trading has a big difference so you can't really compare their earning possibilities. There is also no set of risk ratios here. As far as your trading progress is concerned then just keep it that way. Good for you that you are getting positive results on your spot trading.
However, you should not disregard the risks while being comfortable with your current doing. The reason I said that is because you mentioned that with spot trading, you are not bothering yourself with the fear of losing trades. There's no perfect trade, even the hardcore and professional ones, and there will be a chance that you will experience it later on. But because you are not bothering with it, that losing experience might affect your trading views.
Good luck then and just build experience.
