Not sure what you mean, Francis.
The total amount of money you'd have at the end of each day would be double the amount you had the day before. That always ends up an even number, except for the first day.
Doesn't matter if you're given the money or you earn it.
Day 1: Start with $1.
Day 2: Earn/Receive $1, end with $2
Day 3: Earn/Receive $2, end with $4
Day 4: Earn/Receive $4, end with $8
Day 30: Earn/Receive $268,435,456, end with $536,870,912
