Key Takeaways
- Stablecoins bridge fiat money and cryptocurrencies by maintaining price stability.
- Pegged to assets like fiat or gold, they offer lower volatility than typical cryptocurrencies.
- They enable faster transactions, lower costs, and safer crypto ecosystem fund storage.
- Traders use stablecoins to hedge against volatility between trades.
- Algorithmic stablecoins carry higher depegging risks compared to collateralized options.

Stablecoins are cryptocurrencies pegged to a specific asset, most commonly the US dollar. Unlike highly volatile assets like Bitcoin, stablecoins aim to preserve value for everyday use. Popular examples include:
- Tether (USDT)
