Hello, I was just thinking about the two main things I do with bitcoin on a regular basis: Mining and Investing. I was wondering if there was some way to combine them, such as a pool that you mine at, and they invest the coins you mine as you choose (like a more secure 1.0-1.9%, or the PPT at 6.5-6.9%), investing on a daily basis the coins that your miner generates. Your coins would be locked in for a week after mining (perhaps longer for things like hashking's 1.9%), and then they would be withdrawable at any time (factoring in pirate's withdrawal wait, perhaps within a day?). This could effectively work as a ~106% mining rewards pool, and could be relatively simple.
Is there already a pool like this?
