What you really should be asking is why you have not paid attention? Did we not say that Bitcoin and other cryptocurrencies were not the gamer currency? If you think about it, a farmer has many crops. In a plot the farmer may have one row of corn, another row of peas, then still another row of peppers. This means the harvest when each crop is ripe will bring in the amount of currency for that crop.
Did you know that this is how you are suppose to mine? Does not each coin mine a specific way and when each coin is at the trading point, is it not able to be like the crop harvested? I have always tried to get you to think and using thought provoking articles to see that you need to do things your way.
Watching youtube with false people just wanting views and revenue do not even remotely understand the block-chain or how to best utilize your equipment. The only way you will benefit is to understand what algorithm your hardware thrives on.
Some older computers work very well with the algorithm “yespowermgpc” All you have to figure out is what to do with that. As I have stated before Zergpool is easier for you, you should not listen to anyone else. You should however learn what your computers are capable of and work accordingly.
I hope this helps you understand the best way to understanding what works for you.
