Some times I usually think of the reason people are afraid of investing in cryptocurrency, despite the its value and durability, cryptocurrency is a standards investment that will always give the investor the chance of becoming a millionaire due to its appreciative nature, people fail to understand the fact behind cryptocurrency investment, most times the people trying to invest may not have a maximum knowledge of cryptocurrency.
There are numerous factors as to why a person may feel inclined to be fearful in investing in cryptocurrency. As you said, not having the proper knowledge behind the concept of cryptocurrency and its role in society is one major key. Also, a vast majority of people are pulled towards stability, especially when it comes to finance, so if the news or media outlets are speaking negatively against cryptocurrency or there is a huge drop in the market which causes loss in investment, it is not going to be attractive towards people who are not interested in its risks. Cryptocurrency can be a way to get rich quick, and who doesn't want that, but it's not a simple means towards that end, which can be intimidating to people who are skeptical about putting the time, energy, and money into something less concrete than what they are use to.
