I prefered trading to mining as far as trading is concerned I was personally involved in trading and I have seen a lot of prospect in trading to mining although some losses might be incurred while trading but in a long run a trader will be profitable with a proper money management.
I'll prefer trading for now too but I have my partner whose taking sometime to keep himself welcomed on mining. We're not going to mine bitcoin anymore as the difficulty gets higher, we're going to go with alt coin mining. It's almost the same with trading, we mine alt coins and just sell it as trading does. Both are profitable.
I prefer trading since i have a lot of stock and i can manage my losses, this would be the best way in earning money just like mining you can also get coins unless the difficulty level its not too high, and the concept is almost the same.
It's the good thing in trading, when we loss some profit. We had to take advantage of it to buy back to get more chances to get that profit back again. And while in mining the difficulty is just increasing because that source of income is becoming crowded by too miners at all. So I have some feeling that for the next years to come only big miners will profit on it.
