Mining Farms are believed to help keep the crypto in circulation, and for the most part this statement is true. The problem is that smaller mining operations have found a way to be more profitable and use the real life lesson of Humanity Helping Humanity
How Pools like ZPOOL.CA actually work.
Miners running mining farms do not want to keep upgrading their hardware, spending more to keep on top of the difficulty rising, so they have figured out a way to funnel Multiple miners running whatever power they are running, usually within a certain limit, to mine and make good. NO THEY DO NOT MINE BITCOIN!!!!!!!
What I am about to show you is the coin I switched to today, XVG. You will see the coins they are mining. By using the miners hash power, combining with their own, they have multiplied, let us take an example, 430 THS/s to 112 PHS/s. And they do not need to purchase any more equipment because all the miners work together to help each other out. (CODE OF ETHICS)
Note the right column, these are the coins being mined by the hash power I am assisting with on top of their own. Multiple coins being mined instead of waiting long hours for blocks of Bitcoin, it racks in the smaller coins. This in turn has to go to an exchange and sell to pay you in the coin you want to be paid in, In this case I asked this coin to be paid in VXG.
When these go to the exchange it helps with the volume, as well as the price. This way it is a full circle. Now let us look at a coin I just switched to at 10:45 PM last night Bitcoin Cash (BCH)
As of 10:45pm last night this is how much BCH I have mined, and it is not even 24 hours yet. Now the below picture will show you what coins they are mining
As you can see, when you put aside greed, and work as humanity should a team, everything works better.
