I noticed that there are many investors who likes to participate during ICO because of the huge profit but its very risky as well.
When is the best time to buy Altcoin?
ICO stage?
From Exchange?
Wait for the dip?
The altcoins that are already in exchange, in my opinion, are much better. However, there is a need to be noticed before deciding to buy altcoins. Check and learn sales graphs. Don't rush to buy coins before you do it. Altcoins nowadays may be much better and the price slowly grows due to considering Bitcoin prices continue to rise.
