dont waste your time and money.i can tell you.you will hit the wall:-)If difficulty is high and you have low hash power you will hit the wall just like i did:-)
It is just comparing doing mining on the large and small pool and of course with the same coin so the difficulty would be ignored.
I've been doing something like this before, but I'm doing for my self. Comparing one pool to the other, large pool and a smaller one.
I think if a large pool means the pool with a large hasrate, it will have a few possibilities related to miner profit.
-) If that large hashrate comes from a lot of miners means the block reward will spreading to many miners that mine at that large pool, but the pool has a good chance of solving many blocks.
-) If that large hashrate comes from only several miners means each miner that exist will get more share.
and also,
-) (Share) will depend on the pool's payment systems that used.
That also will happen in a small pool. If the small pool means the pool that has small hashrate.
-) If that small hashrate comes from a lot of miners, it's terrible things because besides the pool have a bit chance of solving a block, the block reward itself will be shared to many miners.
-) If that small hashrate comes from only several miners means each miner that exist will get more share and sometimes doing mining on this kind of pool more profitable than a large pool with many miners.
I didn't finish watching that youtube videos
