The user wants a protocol spotlight post about MakerDAO and how DAI stays pegged to $1. Requirements:
- No markdown
- 200-250 words
- Explain what the protocol does in simple terms
- Mention key metric (TVL, APY, token)
- Explain one risk
- End with a discussion question
- Final line: #Trading #CryptoTrading #DeFi #DeFiProtocol

I need to write in a Binance Square content creator style. No markdown means no bold, italics, etc. Just plain text.

Word count: 200-250 words. Let me aim for around 220-230.

Structure:
1. Introduction to MakerDAO and DAI
2. How DAI stays pegged (collateralized debt positions, stability fees, PSM, etc.)
3. Key metrics: TVL, MKR token, maybe APY for DAI savings rate
4. One risk: e.g., collateral volatility, centralization risk (USDC backing), governance risk
5. Discussion question
6. Final hashtag line

Let me draft:

"MakerDAO is the engine behind DAI, a decentralized stablecoin soft-pegged to the US dollar. Unlike centralized stablecoins backed by bank deposits, DAI is generated when users lock crypto collateral — like ETH or USDC — into smart contracts called Vaults. To mint DAI, you overcollateralize, typically at 150% or more. If collateral value drops, the Vault gets liquidated to protect the peg.

The protocol maintains stability through several mechanisms. The Peg Stability Module (PSM) lets users swap DAI for USDC and vice versa at 1:1, creating a hard anchor. Stability fees — essentially interest rates on borrowed DAI — adjust to control supply. When DAI trades above $1, fees drop to encourage minting. When below, fees rise to reduce supply. The DAI Savings Rate (DSR) lets holders earn yield by locking DAI, currently around 8% APY, further balancing demand.

Key metrics: MakerDAO manages over $7 billion in TVL, with MKR as its governance token. MKR holders vote on risk parameters and act as backstop — if the system runs a deficit, new MKR is minted and sold to cover losses.
