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?
Now there is a really difficult situation on the market and you correctly noticed that some projects started selling ETH in large quantities, which affected the price reduction. Nevertheless, this is a good time to buy coins on the market, as prices are low and many people will see further growth and recovery in the market.
