It's actually not that risky if you do lots of research. Its risky for the idiots that throw money at anything that is hyped up with lots of advertising.
I agree. But then it has still risk but with enough knowledge that can be gained through research and such, the risk will be lessened. Not really eliminate but only lessened. Proper research is the key for you to avoid scams. You are just in risk if you are not smart enough and wise in making decision.
