I agree with you. Every currencies will be digitalized in the near future. Cryptocurrencies will help to democratize the economy. We can see successful case with Zimbabwe, the hyperinflation crisis during 2008 and 2009 cause many citizens to lose huge amount of savings and they were in need of to secure their own savings. And now, bitcoin have accelerated their economic growth rate. I hope there is gonna be positive news of country legalising cryptocurrency as national currency.
