Well, from my point of view, cryptocurrencies can help a lot in the financial inclusion of individuals, since they do not have as many restrictions as the traditional financial system, according to official data, global transactions have increased a lot since cryptocurrencies were born, and many of the people who use crypto are unbanked people, on the other hand, they are very good at sending money anywhere in the world, they are perfect for cross-border transactions.
Crypto can also be a tool in the future to combat prevailing inflation, especially those deflationary currencies. On the other hand, coins like Bitcoin that have a transparent, accessible and public blockchain could help fight embezzlement and corruption since we could all access transaction data and where public and other money would go.
