Final Thoughts: The Right Stablecoin Is the One You Use
There’s no one-size-fits-all stablecoin.
Instead, ask yourself:
- Are you spending or saving?
- Are you risk-averse or DeFi-native?
- Do you need compliance or decentralization?
Your goal determines your coin.
And the good news?
You can always split across multiple stablecoins to reduce risk.
