Buying ICO’s and altcoins are like investing in IPO’s and Penny stocks.
Lots of potential reward, but real risk that you may lose up to all your investment. Many ICO’s are for coins that have no practical use (you can’t buy anything with them) – only an investment value that may plummet at any time. For Example, Bitcoin can be used to purchase goods and services from many established companies. Altcoins need to be on exchanges, where they can have a value equal to Bitcoin (BTC) and other coins, so the altcoins can be traded.

Going “ALL IN” my be fun, but figuring where to start taking profit is a mystery, and many investors have watched their value climb, and then plummet, with little warning. Remember, any profit is good profit.
