We can't afford not having people on our side doing the mining; if honest miners don't hold the line, we risk getting screwed by dishonest ones.
Which is why ASICs are so good.
Common joe's can buy a one or two and join a pool.
90 ghs will be worthless in 6 months time . this is what i think. bitcoin will become what it hates the most!
Such a misinformed and false opinion. There are a lot more variables than expected profit and hashrate.
I guess, most people see the charts from 1-2 years and they think everyone got huge profits with mining. It was not the case. timing, exchange rate, cost of hardware and power are as important now as it was back then.
This is not a great time to enter mining - that is true - but it doesn't mean that it will never be a good time in the future.
Look out for next gen asics and place orders in the first 2 batches.
As for having a few companies "owning" the network would cause these comapnies to go bankrupt. Centralization is not in their interest. Bitcoin main strength is it's peer to peer nature.
