There are many fraud projects and it's better to do research. New coins entering the stock market tend to decline and prices are definitely below the ICO price. This might be an annoying thing because the coins have not been sold, we have got a loss. Even if the coin is held until the price rises again it will take a long time.
be careful before joining the project and of course you know everything first, to avoid bad things. lots of evil coins and fraud, so you will be trapped if you are not careful. a lot of ICO fraud but not all ICOs are bad, you have to be careful and find out more so you can succeed.
