Trading is very risky and I think, the disadvantages is higher that the advantages because you will end up in losses in the long run. However, the trader using risk averse strategy wouldn't be affected by much losses because it's clear that he's trading with what he can afford to lose but I don't like using stop loss.
The advice that I do give to traders is not to open to position when you don't understand the market because if you do, it means that you are gambling.
People that wants to trade makes a big mistake of pressing too hard towards making profit but with little attention to how best they can be able to preserve their capital also while trading for profit. There has to be some balance on the scale, unfortunately, every strategy is mostly about the making of profit, risk management doesn't receive attention that much that's why it looks like there's a huge disadvantage for traders.
And yea, opening a position for the sake of it instead of out of clear analytical understanding of the trend is something all traders should avoid. Trading against the market trend is another mistake made by some traders, it's as though they're testing their luck on the market.
