echo "INBOUND FEE STRATEGY SUMMARY"
echo "═══════════════════════════════"
echo ""
echo "POSITIVE INBOUND FEES (+5 to +150 ppm):"
echo "✓ Prevent outbound drains on valuable channels"
echo "✓ Compensate for providing liquidity"
echo "✓ Signal that your inbound liquidity is valuable"
echo "✓ Maintain channel balance longer"
echo ""
echo "NEGATIVE INBOUND FEES (-10 to -50 ppm):"
echo "✓ Attract routing to rebalance channels"
echo "✓ Activate dormant channels"
echo "✓ Backwards compatible (discount on total fee)"
echo "✓ Compete for routing when you have excess liquidity"
echo ""
echo "ZERO INBOUND FEES (0 ppm) - Current default:"
echo "• No additional incentives or disincentives"
echo "• Standard routing behavior"

echo ""
echo "💰 PROJECTED REVENUE IMPACT"
echo "═══════════════════════════"
echo ""
echo "Phase 1 (Drain Protection):     +3,000-8,000 sats/month (prevented losses)"

echo "═════════════════════════"
