One way for digital currency to be adopted by the public is by campaigning positive things about digital currencies, especially cryptocurrencies. Because basically fiat currency and digital currency (crypto) also have similarities. that is, both are acceptable because trust functions as a medium of exchange.

Fiat currency is believed to have value and is trusted as a medium of exchange because it is issued by the government. While crypto, although not issued by the government, more and more people believe it has value, and as a medium of exchange. For example, Tesla, which once bought bitcoin, and discussed accepting payments in bitcoin for the purchase of its production vehicles (though not now) while still subject to regulations in each country, which are still limited to date.
