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.
this is a very complicated subject, I say complicated because I have seen very strange things, I will tell you what I saw and see:
I find scam ICOs, created a thread exposing the ICO is scam and after post in the ICO thread to warn people that the such ICO is scam and guess what happens after I post in the ICO thread? all people ignore me, people continue to post in thread of the ICO as if nothing had happened.
The same thing happens with exchange, how many accusations does yobit have? There are a lot of accusations, but people still use yobit.
The people scammed by yobit are probably less than 5% of all yobit users.That's why nobody would respond to such scam accusations.ICOs are a different topic.It's difficult to figure out when some ICO project will turn into an exit scam.The ICO dev team keeps updating the crowd with "news" and always has excuses,when something suspicious happens.Meanwhile the coins gathered from the ICO are gone...
