I will disagree with you. As we see, unfortunately, many ICOs vanish and people simple lose their money forever. When you invest in altcoins, you know that you will have the returns in some time.
We don't need to invest in ico token new listings on the market. We could invest it altcoin which is a top 10 market. I think it is a great option. token ico is now very detrimental, but a token already listed on an Exchange could be very profitable. now altcoin are cheap, of course this is the right time to invest.
