Better or not, at least cryptocurrencies are an alternative. One of its interesting features is that make people more responsible about their money. With crypto you cann´t use your credit card to buy things with money that you will have to return later with interests. With crypto you can have more control of your funds.
Asides having more control over funds, I guess it has opened people's eyes to why saving is better after all. Most times with fiat, we save in banks, they use our cash to trade and we even still get some debits in return. Highest stealing of the highest order.
With crypto on the order hand, at least I know saving my cash gives me the opportunity to make it do better for me and also capitalize on its value increase.
