If you invest in altcoins and you make exchange buy/sell orders then this is the risky part.
Because you never know how high or how low will the exchange rate go, and I lost a lot because of high dumping.
But if you invest in ICO then this is another thing, you should risk and search more about the project how it is going.
If we tend to choose on ICO we should really find important informations and deep research regarding on that coin because its not really easy to choose the profitable ones because there are lots of coins to choose from.If you select the wrong one then say goodbye to your money.
