Whether or not they should be scared--they are not scared. It is the "hype" behind many individuals getting involved that has spiked the market cap in the last few months. The key word there being Individuals. Many corporations and institutions are not yet involved--but they are looking and interested. This "mania" that has taken the crypto market by storm the last few months is fueled by a lot of people that don't know much about crypto--they just see the massive returns and assume that crypto is "guaranteed gains"--it is nothing of the sort and when a big dip happens, many of these new-comers will experience it for the first time and mistake it for a crash. A massive pull-out from new buyers could possibly trigger a crash. The big institutions, power groups, and governments do not take us individuals seriously, and I don't blame them at this point. One step at a time though, if enough smart investors remain true to the course, crypto will begin to command the attention of big banks and governments. Not yet though.
