The European digital euro has moved forward once again, and the timeline is now clearer. It will still take several years to implement, but the direction is already very clear: the fiat currency payment system will not remain in its current state.

Later on, stablecoins, cross-border settlement, and payment gateways will be repeatedly compared, with compliance and efficiency becoming key metrics.
