4.5.1. Pros

4.5.1.1. Pooled mining generates a steadier income.

4.5.1.2. Pooled mining can generate a 1-2% higher income (before fees, if any) due to long polling provided by the pools.

4.5.2. Cons

4.5.2.1. Pool mining can suffer interruptions from outages at the pool provider.

4.5.2.2. Pooled mining tends to generate a smaller income due to fees being charged and transaction fees not being cashed out.

4.5.2.3. Pools might be part of attack scenarios.

4.6. Solo Mining

4.6.1. Pros

4.6.1.1. Solo mining is less prone to outages resulting in higher uptime.

4.6.1.2. Solo mining doesn't incur any fees. For each discovered block, 25 BTC and the transaction fees are paid to the miner.

4.6.2. Cons

4.6.2.1. Solo mining tends to generate more erratic income.

4.6.2.2. Solo mining wastes time due to only supporting getwork pull.

4.6.2.3. Solo Mining needs a large amount of hashing power, thus it's almost impossible to do with bitcoins, while mining alt-coins in solo mode is still acceptable
