What if we told you that we could give you two options...
One is that you get $1,000,000 today OR you get a single penny today and it is doubled every 30 days? What would you choose?
At first you may think well $1,000,000 today sure would be nice. However, you are missing out on the fact that in scenario 2 you would have $5,368,709.12 after a month.
It seems unreal, but that is the power of compounding interest.
