I think it will be great to choose trading, they are both profitable but the trading process is way more better in mining in terms of high income and feasible result.
Mining is most subject in scam schemes which is very alarming and very difficult to trust with in this industry.
These two choices are equally risky. In trading, we get a bigger profit than mining, but that comes back to 'how much capital we spend' and 'how luck we are'. If we are people who like challenges, we can choose to try both of them using the same capital. After we know the difference, then decide which one to take. This maybe, not everyone can try this kind of method, because this requires huge capital. But this will be very useful because we understand from the experience that we went through alone.
