# Micro-Funding Mode Notes:
#
# With 0.001 ETH and max 0.0005 ETH per trade:
# - Estimated capacity: ~2 trades before refill
# - Focus on highest probability opportunities only
# - Use Balancer flash loans exclusively (0% fee)
# - Minimize gas usage at all costs
# - Alert on low balance immediately
#
# Expected Performance:
# - Trades/day: 1-3 (very selective)
# - Avg profit: $2-5 per trade
# - Risk: Very low (small position sizes)
# - Refill frequency: Every 1-2 days
#
# Recommendations:
# - Monitor balance closely
# - Consider increasing to 0.005 ETH for better capacity
# - Expect fewer but higher-confidence trades
# - Gas efficiency is critical - bot will be very selective
