Ignorance is one of the major problems why people don't invest in Cryptocurrency, making people do not understand how to buy and sell in the crypto world, a good number of people lack this understanding and they claim it is insecure to invest into.
There are many reasons why ignorance becomes a serious problem. Not everywhere people are familiar with digital investment, some people even aren't familiar with the internet yet. For these people, surely they assume crypto is something too risky and they may not believe that it can gain money for them. So, we can understand if they are not involved in crypto. In addition, I think people still have a lack of understanding about crypto due to their old habits, not everyone has the ability to follow the innovation. Most of them are old people, they only believe in something that they often do in daily life. They are against something new, especially for digital matters. I saw there are many old people with this personality in my town.
Yes you're right the older people can use ignorance as an excuse due to lack of understanding of the digital world or inability to operate the modern gadgets or browse the Internet and learn, but how about the younger generation like the mid twenties and adults below 50's would they use ignorance as an excuse as well?
