I am new to mining. I have several S3's and an S4 and have started mining today.

What I have noticed as a relative outsider is the following:

Whatever your hashrate, you will only earn money when your pool finds a block. So when all the pools that you are not with are finding blocks, your own pool is eating up electricity for nothing. I noticed in some pools that it took a massive 6 hours to find a block.

Have I got this wildly wrong or should all pools integrate into one big one?
