This is really low. And you can withdraw from pool at any time with lightning? I started the other way around. But stopped solomining some time ago. If your hashrate is constant you can sell it to plebs on a daily basis. They probably pay you more. Or you can make some special deals like 1-10% of blockreward go to you if a block has been found. What if your Bitaxe really finds a block while mining for a pool that pays you 32sat a day and even keeps 2% of it? It is not impossible.
