I saw some videos where a single home laptop can run a mining software and collect fractions of Bitcoins every now and then. However, a mining reward is a full 25 BTC. My questions:
- Does that mean that the mining software joins my laptop to a pool?
- If yes, then if I get fractions of a BTC over time, does that mean that my pool succeeded in resolving a block and collected 25 BTC?
- If yes, how is the reward distributed?
