$LINK The idea of cryptocurrency is precisely to be decentralized, not to depend on central banks or governments. But in practice, for spending in daily life, most places do not accept it directly. So you need to convert it to fiat currency (real, dollar, euro, etc.), which is like taking two steps back: you return to the centralized system that cryptocurrency theoretically wanted to avoid.

The card brands, under pressure from governments, will never let this move forward! In the end, it’s just a place to store money!
