Just like almost everything in life, even living itself, there are risks associated with investing in cryptocurrencies. One of the reasons for people are faced with these risks anyway is mal-information, or inadequate knowledge which makes them make decisions that can cost them a whole lot. When you don't have the right knowledge, you might end up making bad investment choices, which can lead to loss of funds. This is the major risk people are aware of, and are scared of as well.
Many people are misinformed because they chose to be misinformed and there is absolutely no one forcing them to accept the information before they first verify it. People always listen to opinion too much rather than heading for a better research on any decision they wish to make, and this is why many people have fallen victim of some of these scam projects and hackers.
Life is full of risk generally, but we have so many strong people that have always learnt to deal with the associated risk everyday of their life and they have been succeeding in dealing with it. The only risk that is most found with cryptocurrency which we cannot blame anyone that falls into it too much is just the volatility, decisions being made during this period is not that easy, and except that, everyone that has made wrong decision is to be blamed for their action for not being able to manage the risk involved.
