yeah but what the difference between 4+ pools having 10% and 3 having 33%(for example), in both case it does not look centralized to me
as long as there isn't 1 pool controlling everything, it can't be said that it is centralized, at least that's how I see it
You said 3 farms not pools. There is a difference. It's much worse to only have 3 farms.
A pool is a group of miners (i.e. farms). A farm is just a single farm run by a single person or group of people.
this home mining worth ?
i going to will buy 50 miner and worth 50 miner that will buy ?
i will be problem and don't will be income ?
i want that living mining and i'm interested worth ?
Mining in your home is not worth it. If you buy 50 miners today they will definitely lose value because new miners are being released regularly.
There is quite a good chance that you're going to be losing money.
Home conditions mining in future isn't problem ?
worth that i will buy 50 miner and i will begin serious mining ?
You can't mine using 50 miners in a home. If we assume that they are the top models; you don't have such a power supply to your house and you don't have proper cooling.
