As ASICs become more efficient, and expensive, fewer people will mine. The people who do mine have capital to purchase expensive machines, and the largest operations will have the most efficient setups. As fewer and fewer people are able to afford efficient ASIC miners, the network becomes more centered around more wealthy individuals. Is this a bad thing? What is BTC backup plan, in case centralization becomes a huge issue?
You dont need to mine to get btc ...
simply buy 1 btc for 400 usd today, its 65 % cheaper than in December 2013 ....
and become part of "centralised" bitcoin if you want .. go on ..
Sorry I but i totally disagree with you
