What is
Стейблкоины?
Стейблкоины — класс токенов со стремлением к стабильной стоимости (обычно привязка к фиату).
Под стейблкоинами понимают токены, которые стремятся сохранять стабильную цену. Реализаций много: централизованные обеспеченные, децентрализованные обеспеченные, алгоритмические и гибридные. Каждый тип имеет свои компромиссы по рискам и устойчивости.
Key Points
- Стабильность достигается разными механизмами
- Компромиссы: централизация vs устойчивость vs ликвидность
- Риски зависят от дизайна и рынка
- Важно оценивать прозрачность модели

How to get started with Ergo?
Start by getting a wallet (Nautilus for browser, Terminus for mobile). Back up your seed phrase securely offline. Get some ERG from an exchange (Gate.io, KuCoin) or DEX (Spectrum). Make a test transaction. Then explore: try DeFi on Spectrum, check out NFTs, or dive into the technology if you're a builder.

Is Ergo a good investment?
This is not financial advice. Ergo has strong fundamentals: fair launch (no VC dump risk), innovative technology (eUTXO, Sigma Protocols, NiPoPoWs), active development, and a cypherpunk ethos. It's a smaller market cap project with higher risk/reward than established chains. Research thoroughly, understand the technology, and never invest more than you can afford to lose.

What is SigmaUSD and how does it work?
SigmaUSD is Ergo's algorithmic stablecoin, pegged to USD and backed by ERG reserves. It uses the AgeUSD protocol: users mint SigUSD by depositing ERG, while SigRSV holders provide reserve backing and absorb volatility. The reserve ratio (400-800%) ensures stability. No centralized issuer, no bank accounts - pure crypto collateral.
