Define wrong ICOs? this actually leads to a good and most appropriate investment. But there will always back to investor, we cannot judge wrong when others maybe say true. And like kryptqnick say people invest is not for losing money. So they must be do their own research before investing.
Defingin a "wrong" ICO is of course impossible, I did not mean it so bluntly.
It is the way so many people talk about whatever has managed to spend money on creating a fake hype - and that is then followed by disappointment down the line.
In my eyes the market has changed - before a large chunk of ICOs were short term positive because everything was hyped.
Now, the research has to go beyond the immediate ICO listing "pop" - the easy money is gone.
But I truly believe among all the rubbish there are real projects such as Prosume Energy and Grid+.
