Why do stablecoins exist?

Crypto is volatile. Bitcoin can rise 10% or drop 15% in a day. Stablecoins allow you to get out of volatility without going to the bank, operate DeFi, make arbitration, maintain liquidity quickly and protect capital temporarily. They are the "box" of the crypto market.

Types of Stablecoins

  • 2.1 Stablecoins in cash (fiat-backed)

Examples: USDT, USDC. For each token issued, there is theoretically 1 dollar stored in reserves. They are centralized. There is a company behind. You trust that reserves exist, are audited and are accessible. It is institutional trust.

  • 2.2 Stablecoins collateralized in crypto

Example: DAI. The ballast is not a bank dollar. It is a cryptocurrency traded in smart contracts. To issue $100 in stablecoin, you may need to lock $150 in crypto. This creates overcolateralization. It is more decentralized, but depends on the stability of the collateral and the operation of the protocol.

  • 2.3 algorithmic stablecoins

More risky model. They try to maintain parity through mathematical mechanisms and market incentives. No strong traditional ballast. There have already been large collapses in this model. This type requires careful analysis.

What does it mean to lose the peg?

Peg is the parity with the dollar. If stablecoin drops to 0.95 or rises to 1.03, it is misaligned. Small deviations happen. But if structural confidence is lost, there may be collapse. Stability depends on liquidity and credibility.

Regulatory risks

Centralized stablecoins depend on banks and regulations. If regulators block reserves or require freezing, this impacts. Some stablecoins have the ability to freeze addresses and block funds.

Stablecoins at DeFi

Much of DeFi revolves around them. You can borrow, provide liquidity, use as collateral and generate income. But stablecoin is not synonymous with zero risk. There is risk from the issuer, protocol, liquidity, and the market.

Intelligent strategy when using stablecoins

Diversify between issuers, don’t focus everything on a single model, keep track of regulatory news and understand where you’re saving.

If you are in a broker, the risk is of the broker. If you are in your own wallet, the risk is of the issuer. If you are in DeFi, the risk is of the contract. There is always some risk.

What You Should Take From This Guide

Stablecoin is not “stopped money”.It is the financial infrastructure of the crypto market.

They are essential. But they are not risk-free. Understand the model before trusting relevant values.
