Most coins have lost 50 to 80% of their value, many tokens that were financed with expensive ether may now have their funding reduced due to their holdings. Do you think many of the ICOs have sold their ether and bitcoin during the last months? What other factors are making the market go steadily down?
A lot ICOS have actually sold off all of their ether and bitcoin holdings and that is why you see that so much money has left the market in such a short time. It is one of the reasons that the market is in a dip right now. If you are going to invest then really now is the best time to do so because the coins are so cheap. The only place left to go is up.
