Many a trader got scammed in recent years due to the fraudulent projects, no matter if they are ICOs, social media "gurus" or trading platforms. In my opinion, it would be important to first educate beginners (here's an article on how to avoid mistakes, scams included
https://www.cryptocointrade.com/education/avoid-cryptocurrency-trading-mistakes/). How do you figure one out and what can be done in near future to limit these frauds an access to the market?
I see that some people here are laying accusations on Yobit. If you say that Yobit is a scam, then why are people still making use of it? A lot of people still make use of Yobit and they are even cashing out from it without any problem. Same as I have seen a lot of people call Binance and Bitfinex scams too, but there are still people who trade with these two sites and are making profit daily and even cashing out without having any problem. If anyone as having problems with these exchanges its possible that you might have disobeyed one of their rules and regulations.
