Do you ask yourself these questions?
How can I watch the bitcoin exchange rate?
What amount of bitcoins have I mined, but not yet transferred to my wallet, and how much are they worth?
How many bitcoins do I currently have, both unpaid in pools and in my wallet, and how much USD can I get for it?
How many total bitcoins did I mine since I started mining?
I don't mine, but how much is my investment in bitcoins worth in USD (or any other currency) at this moment?
MyBitcoins is a Windows gadget which displays two values: the amount of bitcoins you have, and an estimated value of those bitcoins in your preferred currency.
