Based Bloomberg research $560M flowed into ICO's in June alone. For comparison, angel and seed stage investments run at ~$550M each month. Digital coins are still highly volatile - their market cap is currently around $86 billion, down from $100 billion last week and $115 billion on June 14.
A recent report from CB Insights and PricewaterhouseCoopers LLP shows that $8.7 billion flowed into Internet-related startups in the first half of 2017, and across all sectors roughly 50 percent of investment was in the seed and early stage firms, he said. So taking half of $8.7 billion, cutting it in half once again and then dividing by six to get a per month number gives you roughly $360 million, below the amount of ICO funding seen, Mougayar said.
