Dozens of cryptocurrency companies have given up on their ICO's after receiving a phone call from the Securities and Exchange Committee (SEC). The SEC is implementing traditional methods of warding off shady ICO's and the strategy seems to be working.
On a side note, according to some estimates about $1.2 billion has been invested in ICO's in the first two months this year; this is compared to $3.7 billion in the same time frame in 2017.
