For example, giving proof that his current mining farm does produce 50 bitcoins per month, or uses Binance pool to mine, etc. I don't think that is difficult and break his privacy either if that is an issue.
My personal farm does not produce 50 bitcoins a month
I made an arrangement with another, affiliate farm that has enough sites with the right electrical capacity and is currently actually producing approximately 50 bitcoins a month through the Binance pool.
Proof of my words, apparently, can be provided later.
I am not asking for any investment, so I see no urgent need to prove anything to anyone.
Besides, the point of the pool is to have a LOT of customers and a lot of connected farms, not just one. So even if this farm decides to disconnect, or switch to another pool, or even starrt to mine solo - it should not have a fatal effect on the project.
I've seen a lot of dead pools that have ceased to exist. And if we focus only on the first farm, which I found - we are likely to suffer the same fate.
Of course, maybe we can use some open source solutions like yiimp, but we also need nice client accounts with statistics and good servers with minimal pings.
