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?
I, too, lost 80 percent. But most likely it is artificial spiculation. Soon, bitcoin and ETH will begin to grow and the Altkoins follow them.
