I look at cryptocurrencies as funds that allow ordinary people to participate in investing and get microloans. Of course, the banking system cannot guarantee the security of cryptocurrencies, they do not regulate them. But it remains important that cryptocurrency is a means to generate additional income, which improves the financial condition of a person when the country's economy is not very strong.
When you have a cryptocurrency, you can make transactions with less losses on the commission, but most importantly, no one will forbid you to send or receive funds. I like that I can support projects that seem important and promising to me, and do not even need to have a huge budget. It gives the feeling that you can change something for the better, make a contribution to society. Many investors and politicians forget about this.
