I guess all that can make an income on the internet has a risk level of each. Well, according to my experience, trading is one way to make money on the internet that have a fairly high degree of risk if you do not have knowledge about trading. before trading, you have to learn about it, even very many trading demo version made for beginners. you have to learn to play the trading prior to play it, because it would be risky if not done
It's complicated enough that you can play around for as long as you want and it will still be risky; there are just too many subtleties involved to pick up on all of them by yourself.
Let's follow Wall Street then, they can't be wrong, right?! Sharpe ratios, mean reversion, averaging down, fundamental analysis, all that crap. However, Wall Street has no incentive to make money on the long run, because they get rich in the short run (and then they blow up their customers' accounts, but who cares when they already got their bonuses?) So, let's not follow Wall Street... But who, then?
The problem I found was that most information out there are from clueless idiots such as myself. It took months to find a few sensible sources, and they are invariably people with institutional background (i.e. they actually did what they are talking about), who then de-institutionalized themselves and fared well on their own (i.e. they actually know what they are talking about.) They are the people to listen to, not the charlatan mentors who will sell you their crappy strategies full of Fibonaccis and wave theories and 6-month plans and other mindblowing idiocies.
