Many people using Bitcoin needs to check on a daily basis the current value of their satoshis. I developed this calculator application for people who need to calculate the Satoshi to USD value on a daily basis.

Income: You will get referral income in Bitcoin from the Exchanges. It is very simple to add more affiliate referral exchanges later on. All you need is basic HTML knowledge. This is an everyday application which means income can be generated on a daily basis. 

When you check the amount of Google Searches per day on converting Satoshi to USD, you can see the potential.
