SEC steps up scrutiny of digital coin sales with order to freeze 'PlexCoin' founders' assets
The Securities and Exchange Commission says it's obtained an emergency court order to freeze assets of those behind an initial coin offering that falsely promised a thirteenfold profit in less than a month.
Under that false promise, PlexCorps had raised up to $15 million from thousands of investors since August, the SEC says.
It's really sad to see so many people got scammed and $15 is just wow...
