How does this work?
Day 1: $10,000
Day 2: $10,000 + 10,000 = $20,000
Day 3: $20,000 + 10,000 = $30,000
Day 4: $30,000 + 10,000 = $40,000
Day 5: $40,000 + 10,000 = $50,000
Day 6: $50,000 + 10,000 = $60,000
Day 7: $60,000 + 10,000 = $70,000
Day 8: $70,000 + 10,000 - 10,000 = $70,000
Day 9: $70,000 + 10,000 - 10,000 = $70,000
Day 10: $70,000 + 10,000 - 10,000 = $70,000
Day 11: $70,000 + 10,000 - 10,000 = $70,000
Day 12: $70,000 + 10,000 - 10,000 = $70,000 ..
