Yeah it is an opportunity if you get to buy ICO coins . But we should be very careful on the selection of coins. We should make a research of the particular coin we are going to buy. Volume of the coin and its market cap are to be observed since that help us to predict whether the coin is worthy or not.
If the coin is good, do buy it because we can gain more profit of it at the end. Because sooner or later everyone will start buying it at the higher price while we would have bought it at discounted rate.
