Buy and run a miner?
With ocean pool?
Solo mining or ocean or send the hashes to the smaller pools.
But will it make any difference?
Not really, if you solo-mine, it's too much headache to create the infrastructure and cooling system for your miner, and you'd be mining in one of these pools anyway. And lose money on a depreciating machine before gaining any meaningful amount of btc. Some mining companies have hundreds if not thousands of rigs and yours will be a pass in the sea
