The truth is large amount of the funds of some rich people have been invested into cryptocurency, especially Bitcoin. While currently there are no known technical cliches that might cause people to double question the safety of their funds. I am pretty sure many investor are damp worried about what will happen to their funds even if Bitcoin and Blockchain face 5 minute offline mode. Just to make it short, it is not only Bitcoin that is risky, the entire crypto world and investment is a dangerous affair
