Why is crypto currency risky?
Cryptocurrency is risk for a number of reasons.  The price fluctuations are usually driven by large institutional investors not individuals.  When institutions pull out their money you can see price fluctuations as high as 90% loss.  It is a deregulated digital currency with no government oversight so if your money gets hacked or taken because a bad actor got your wallet keys your money is lost for good, you will never get it back, and there will never be an investigation into where your money went.  If you are going to play in the crypto currency space its best to use a platform similar to coinbase that has security measures in place for all your crypto wallets so your money doesn't get stolen.
