For example, my local newspaper published a number of articles about a "successful" trader who was offering training programmes. Last month he was sentenced to three years in prison for fraud.
There are numerous examples of this and even "reality" TV shows promoting these people as successful or rich, it is about time the media are held to account.
There are lots of people in social media who pose in front of expensive cars and with designer bag in order to sell their crypto or forex trading training courses. Most of course don't make their money from trading, but from commissions paid by platforms for winding in suckers.
