According to Doctor Nouriel Roubini,
An academic study suggests that 81 percent of all ICOs were a scam to begin with; 11 percent of them have failed or have died; and of the remaining eight percent that is traded on exchanges, the top 10 have lost on average, in the last year, 95 percent of their value — more than Bitcoin. So, there was a bubble — and everybody was riding the bubble, everybody was issuing an ICO, raising money — but now it’s gone bust… I think that they’ve lost already 95 percent of their value and they could lose another 95 percent.”
