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.
I just made me remember all the dozen ICOs around that claims they are going to be the next bitcoin or eth and etc. I'm not mad if they have fear on investing on crypto because I've seen a lot of false claims of projects that just became a total disaster.
