Advanced Tips: Optimize Your Yield and Manage Risk
Understanding Fixed vs. Variable Interest Rates
- Fixed Rate: Set by Sky Governance. It remains stable short-term but may adjust via governance.
- Variable Rate: Adjusts dynamically based on market supply and demand.
Which to choose? Opt for a fixed rate if you prefer stability. Choose variable if you're seeking higher returns and can tolerate volatility.
Health Factor: Your Risk Indicator
The Health Factor indicates the safety of your borrowing position. It reflects the ratio between your collateral value and loan amount.
- Health Factor > 1: Safe.
- Health Factor < 1: Your collateral is at risk of liquidation.
Common Mistake: Ignoring the health factor and getting liquidated.
Tip: Monitor your health factor regularly and adjust positions accordingly.
Avoiding Liquidation
To prevent liquidation:
- Add More Collateral: Increase your collateral to improve the health factor.
- Repay Part of Your Loan: Lower your outstanding debt.
- Stay Updated: Keep an eye on market conditions and react promptly.
Maximizing Yield
- Choose High-Yield Assets: Some assets offer better APY than others.
- Leverage Market Conditions: Time your lending and borrowing during market fluctuations.
- Diversify Your Portfolio: Spread your assets across multiple markets to reduce risk.
