The team of Ifan and Pincoin disappeared after collecting $660 million from approximately 32,000 people.
Quoted from Techcrunch "This so-called exit scam could be that largest in recent memory and is also indicative of what’s to come in the ICO space". The question is how this ICO which was allegedly multi-level marketing could easily made this happen, the fact is this kind of ponzi schemes already spotted on before here. People are too hive with ICOs and they're just coming in treating cryptocurrency as a quick buck scheme.
