Magic doubling account

What would happen in one day if you have a bank account that doubled in value every hour and you deposited 1 penny in it at 12 : 00 am? 

You have one penny and it doubles in value every hour. How much money would you have after one day? 

• At 01:00, you would have 2p.
• At 02:00, you would have 4p.
• At 03:00, you would have 8p.
• At 04:00, you would have 16p.
• At 05:00, you would have 32p.
• At 06:00, you would have 64p.
• At 07:00, you would have £1.28. 

It took the first seven hours of the day to make over £1. So you are waking up to seeing just over £1. 

• At 08:00, you would have £2.56  
• At 09:00, you would have  £5.12
• At 10:00, you would have £10.24 

It is still the morning and you have already made £10. 

• At 11:00, you would have £20.48 
• At 12:00, you would have £40.96  

Half the day has gone by and you have made £40.96 from 1p. 

• At 13:00, you would have £81.92 
• At 14:00, you would have £163.84
• At 15:00, you would have £327.68

At the time of me writing this article most Brits make less than £100 per day. By 3pm it is clear that you have made more than most Brits make in one day because you have £327.68 and you still have 9 hours of the day to go.

• At 16:00, you would have £655.36
• At 17:00, you would have £1,310.72

So you get home and start making your dinner and realize that you have over £1000  from 1p 

At 18:00, you would have  £2,621.44 
At 19:00, you would have £5,242.88
At 20:00, you would have £10,485.76 
At 21:00, you would have £20,971.52 
At 22:00, you would have £41,943.04 
At 23:00, you would have £83,886.08

Then finally at midnight you have made a whopping 
 £167,772.16 from 1p 

At the time of me writing this, most Brit's make less than £50 thousand per year. If you doubled 1p 24 times you would have more than three times as much.
