Crothian, working alone, at a slower pace than he is currently going, would reach 1,022,593 money on day 125.
I've attached the simple excel sheet for calculating your totals up to day x. It goes out to 410 days (way more than necessary) so it should be easy to see where the numbers get rediculous. A lower interest rate on the bank would be keen for helping control this situation at rediculous times. I'm all for more money from posting/viewing content instead of just "get to point Y and then live off the interest."
