I think that many simply do not understand this and on this they are afraid. Because it is a complex technological thing requiring experience. Many people simply do not know how to use a computer, not to mention such a complicated world as crypto-currencies
Experience is not only the requirement to invest in cryptocurrencies. The main point is to adapt the modernization on how they will invest their money into a legit and safe investment. People are just afraid because of spreading fake ads, fake news and fake sites o invest.
If they don't know the proper technology how can they how can they understand the technology behind the project because we are investing here without knowing the technology whether the on has ability to increase its price. Most of the people afraid because of technology.
