And if so, would that be a good thing for us small people or negative??
I mean rich people are capabale of so much things, so it makes me wonder..
Some rich people are interested in using bitcoin and some are using it already, and I think if they will be using it more that's a good thing. Since it is very unlikely that any rich family would spend over $36 billion to acquire all BTC, I think we are safe.
In fact rich persons using bitcoin are very few and they are way too skeptical so I don't think they are investing heavily in bitcoin. People who are from medium class I see are investing a lot, for medium class I say people who can afford to buy a new car when they want, have nice vacations when they want and don't mind hospital spendings, at least in my country this is what defines a medium class family. Person from these families or young people who are technology related are buying a lot of mining PC-s, I see in my country the RX 480 is out of stock in every major vendor of electronics.
I disagree with this. What about big mining farms with hundreds and sometimes with thousands of Antminers? Only very rich people can afford that. You can mine only altcoins other than Bitcoin with RX 480 these days and although I don't think it's a wrong move to mine them, we have to admit that Bitcoin mining more and more becomes a prerogative of the rich.
