not necessarily, this is a numbers game, the more players you have at the table, the better the odds of finding a block. If what you were saying were true it would make just as much sense to just mine solo vs mining here.
Well, yeah it does make sens to solo mine. The only problem is that it may take several years to find a block, which is why people join pools.
Your XYZ H/s will make the same either way (,assuming it runs for a long enough time span,) unless you're really lucky or you join a pool that's really lucky.
Let's take Phillipma's numbers
He could either mine a kano or solo mine for 535 days:
Mining at kano = ~.02335/day
535*0.2335=12.4995
Solo mining a block = ~535 days
One block being ~12.5
In other words, he's
expected to earn the same either way.
