I myself sometimes complain about fraud ICOs and unstable market. I was very brave while investing many different projects before, but now even if an X coin has 100M USD Market cap, I approach them as if they are insecure to invest. I think the main problem is "trust"
Agree, Trust is the key to everything including investing. Some investors complaining because their trust is reduced and may be due to price movements not in accordance with their estimates so they suffer losses. But overall I think the current price decline is a normal cycle that can occur in any market
