Cryptocurrencies Are the global goal in finance world, unfortnulately global goal for regular people, not for the big boys that can actually make IT happen. A world with one universal currency can make economic global crises vanish like thin ash, problem is that international world banks would be unable to manipulate the values of currencies That's the main problem about making world economy based on one universal currency, anyways hopefully itll happen one day, Because in the End its an inevitable scenario
Cheers
