The Honest Trade-offs
- FDIC insurance: government protection up to $250,000

The Smart Approach: Diversification
Don't go all-in on either. Keep 3 – 6 months of expenses in a traditional bank as an emergency fund. Start with 5 – 10% of savings in DeFi to learn. Gradually increase your allocation as you gain experience. Never invest more than you can afford to lose.
$5,000 in traditional bank (emergency fund)
$2,000 in DeFi (learning allocation)
$13,000 in traditional investments (stocks, bonds)
