Ok so finding blocks is the problem, not solving them.
All the info on Internet like Coinwarz show profit if you find blocks immediately and doesn't allow for looking hours for blocks.
So 1 big pool please, the more pools we get the longer we search for blocks, the less we earn.
1. Finding blocks is salving blocks.
2. The faster blocks are solved the more money you will make; this is true.
3. Its true that the more pools there are the longer it will take each pool to salve a block. This is because while a block will be solved ever 10 minutes (average), only one pool (one miner) can salve a block at a time. Therefor the more pools there are the longer it will take for your pool to salve a block. On the other-hand a single pool for everyone can bring in many more problems. What if the pool goes down? then many people will be pissed off.
