Traders, investors and crypto people in general - like the users of this forum - can use cryptocurrencies in order to make money... Ok
Financial institutions and companies can use cryptocurrencies for quicker and cheaper transfers... Ok
But for teachers, nurses and pensioners, for the grocery store at the corner, the shoes shop, the restaurant, the car repair shop... for these people and businesses what are cryptocurrencies good for? What could cryptos be good for?
They are not night traders. They have no idea what Binance and Coinbase are and they not even think about trading cryptos.
Ordinary people.
What's the point of the existence of cryptocurrencies for them?
How can or could cryptocurrencies serve them?
I will give my personal opinion, with explanations.
Until cryptocurrencies are officially recognized as a means of payment, as we understand, there will be no direct benefit in daily use.
But there is a second "side of the coin":
1. investment instrument. High-risk, but with good potential. And like any high-risk instrument, it can bring a surprise in the form of huge "X's" to the amount of investment..... But it can also bring the same losses

2. Cross-border payments, e.g. using stablecoins. To parents, children, wife, friends,..... - very fast, easy and cheap.
3. As a technology, studying which, it is possible now and with a high probability, tomorrow, to get an interesting and highly paid job.
4. Permanent additional income - airdrop, reward for promotion, signature campaigns at the end of the day
