Frequently Asked Questions
Will CBDCs replace stablecoins?
Unlikely. CBDCs and stablecoins serve different purposes. CBDCs focus on domestic payments and policy; stablecoins power DeFi and cross-border use cases. They may coexist, with CBDCs providing the settlement layer for stablecoins.
Are stablecoins safe?
Major stablecoins (USDC, USDT) maintain reserves but vary in transparency. USDC publishes monthly attestations; USDT has faced regulatory scrutiny. Always check reserve reports. No stablecoin is risk-free — even algorithmic stablecoins like UST collapsed.
Which countries have CBDCs?
As of 2026, China (e-CNY), Bahamas (Sand Dollar), Jamaica (JAM-DEX), and Nigeria (eNaira) have launched CBDCs. The EU (digital euro) and other countries are in pilot stages.
